GTR 2 - FIA GT Racing Game

GTR 2 – FIA GT Racing Game is a sports car racing simulator developed by Blimey! Games and SimBin Studios (later Sector3 Studios) for the x86 PC and is a sequel to GTR. Since its release in September 2006, it has received widespread acclaim. The game simulates the 2003 and 2004 FIA GT Championship racing series. (Wikipedia)

Articles

Why a game from 2006?

GTR2 was/is one of those rare occasions when a game developer is given the opportunity to produce a game as it was meant to be. All the features you see in one game or another but never all in one game these days was actually included in one game: GTR2. And it's still being updated by modders to this day.

Still Beloved and Critically Acclaimed

Here's some links that may give you a better understanding of why a game from 2006 still holds its own:

Community

GTR2 still has an active community mostly around forums, mods, and modding but some online racing leagues still exist.

Defunct:

Getting Started

Getting the Game

Steam is probably your best bet. Head over to the GTR2 store page and pick up the game. It's pretty cheap but offers amazing bang for buck.

Windows XP/Vista/7/10/11+ Compatibility

Try GTR2 first. If GTR2 is running fine for you, no need to worry about this section.

If the suggestions below don't help try reviewing this GTR2 and Windows 11 thread for more comments from other people including generic tips for 'how to run older software on newer windows'.

Compatibility Modes:

  • Steam
    • GTR2Config.exe > Properties > Compatibility > Check "Run as Administrator"
    • Do NOT set a Windows Compatibility mode on either GTR2Config.exe or GTR2.exe
  • Steam with Crew Chief GTR2 Enhancements Plugin
    • Do NOT set either Run As Administrator or Windows Compatibility modes on GTR2.exe or GTR2Config.exe
    • If using DXVK: GTR2Config.exe functionality can be replaced by new GTR2.exe command-line switches and dxvk.conf
    • If you're having any issues check the manual for more details
  • Disc
    • GTR2Config.exe > Properties > Compatibility > Check "Run as Administrator"
    • GTR2.exe > Properties > Compatibility > Check "Run as Administrator"
    • GTR2.exe > Properties > Compatibility > Set "Windows XP SP3" Compatibility mode

GTR2 and Windows 10/11+

You may need to install additional DirectX 9 June 2010 Redistributables (direct link).

If you're really stuck

There's some registry changes for GTR2.exe that may help.

This DXVK Integration > Troubleshooting section may also help in the Crew Chief GTR2 Enhancements Plugin manual.

StarForce Disc Protection DRM

The following applies for Disc versions:

  • StarForce Disc Protection was used at least for the Disc version of GT Legends but it is no longer compatible with Windows 7/8/10+ (see comments here)
  • Never install Official SimBin 1.1: Use No-CD and EXEs from GTR2 and GTL HQ Anniversary Patches
  • Never run EXEs from Disc or Demo downloads
  • You can still use the Disc version after GTR2 HQ Anniversary Patch is installed (May also apply to GTL/GT Legends)

Vanilla GTR2

Competent But Old School

Vanilla GTR2 is GTR2 as is, just install and run the game without doing anything that can't be done by the game itself, such as optimizing, tuning, or tweaking features outside the game, or installing any add-ons the game doesn't allow you to install in-game.

So, for example, you wouldn't clean up the graphics with a custom NVIDIA profile, or improve FFB by editing the PLR, or add high resolution texture packs, etc.

I suspect most people saying "Vanilla GTR2" have tweaked at least a few things the game can't do by itself. So, to be clear, it may be preferable to say a "true vanilla" GTR2 if you've really tweaked nothing outside the game.

Vanilla GTR2 as is is a competent but old school experience. That's why I have what I call #Minimum GTR2 and rarely spend time in a true vanilla GTR2 install.

Minimum GTR2

You can think of Minimum GTR2 as my setup specification for a minimum acceptable GTR2 experience. -Shovas

You don't have to do this right away. You can try vanilla GTR2 and come back to this later. Just know that even a Minimum GTR2 setup will be much more pleasing and enjoyable than a true vanilla GTR2 experience.

NVIDIA Profile Settings

tl;dr

  • Antialiasing compatibility: 0x004412C1 (Diablo III)
  • Antialiasing – Setting: 8xS [Combined: 1×2 SS + 4x MS]
  • Antialiasing – Transparency Supersampling: 8x Sparse Grid Supersampling
  • Anisotropic filtering mode: User-defined / Off
  • Anisotropic filtering setting: 16x
  • Texture filtering – Negative LOD bias: Clamp(*)
  • Texture filtering – Quality: High quality(*)

Considerations

  • I run in Windowed mode, not Fullscreen mode, that may matter I’m not sure.
  • Ensure GTR2’s Video Options (GTR2Config.exe) has Full-Screen Antialiasing -> Disabled (Unchecked)

NVIDIA Control Panel

  • 3D Settings > Manage 3D Setting > Global Settings:
    • Power management mode: Prefer maximum performance

NVIDIA Profile Inspector

Download NVIDIA Inspector, virus scan at virustotal.com, and install.

Run nvidiaInspector.exe, click the Start Profile Inspector button (right-middle), find GTR 2 in the Profiles drop-down, and then set and apply these settings:

  • Reset to NVIDIA Profile Defaults
  • Compatibility
    • Antialiasing compatibility: 0x004412C1 (Diablo III)
  • Sync and Refresh
    • Maximum pre-rendered frames: 1
  • Antialiasing
    • Antialiasing – Mode: Override any application setting
      • Disable in-game Antialiasing using GTR2Config.exe
    • Antialiasing – Setting: 8xS [Combined: 1×2 SS + 4x MS]
    • Antialiasing – Transparency Supersampling: 8x Sparse Grid Supersampling
  • Texture Filtering
    • Anisotropic filtering mode: User-defined / Off
    • Anisotropic filtering setting: 16x
    • Texture filtering – Negative LOD bias: Clamp(*)
    • Texture filtering – Quality: High quality(*)
  • Common
    • Ambient Occlusion setting: High quality(*)
    • Ambient Occlusion usage: Enabled(*)

(*)I couldn’t quickly visually confirm these were actually doing what they should be doing but left them enabled anyway

Caution: Antialiasing can decrease performance. Reduce the setting if it slows down GTR2 too much for you.

4GB Patch

You can allow GTR2 to use up to 4GB of memory (it was developed with a 2GB limit). You may find this necessary as you add more and more mods with new assets that take up more and more memory. So you might as well just do it now.

Simply download the 4GB Patch tool, run it, find your GTR2.exe file, and press OK. You’re done!

The 4GB patch appears to have successfully applied on the GTR2 NO CD patch GTR2.exe file I discussed above under the “Fixing Missing Original Content” heading.

Note: If you happen to overwrite your GTR2.exe file then you will need to run this again. For example, if you rerun the US/EU or NoCD patches mentioned earlier.

Skip Intro Videos

These are always annoying, here’s how to stop them (from PC Gaming Wiki.com GTR2 article):

  1. Open Windows Explorer and find your Steam Library folder for the game: steamapps\common\GTR 2 – FIA GT Racing Game\MovieFiles
  2. Rename (or delete) these files: Intro.bik, GameIntro.bik, SimBin.bik

Defviews.cam Tweaks (Draw Distance, Level of Detail, etc.)

Increase Draw Distance

You can increase the Draw Distance by editing UserData\defviews.cam and changing the second parameter of ClipPlanes to a larger value. I use 100000.000000. For comparison, the original values vary from 500 to 2500, and HQ Anniversary Patch uses 33000.

Caution: On old hardware, this may lower FPS, but on any kind of modern hardware I don’t think you’ll notice.

Increase Level of Detail

Increasing LODMultiplier can increase the Level of Detail. I use a value of 8.00000. In my experience, the original LODMultiplier values (1.0) causes visually noticeable and jarring loading in of high or low detail car models depending on how far away they are from you.

Caution: On old hardware, this may lower FPS, but on any kind of modern hardware I don’t think you’ll notice.

Force Feedback Settings

I highly recommend the SHO Competition FFB mod which crowd-sources wheel-specific FFB parameters and provides PLR files for popular wheels.

Click here to download SHO Competition FFB

This is a little bit obvious, we all go pretty quickly for setting up force feedback, but I felt the need to emphasize this because the default force feedback options are, I feel, not enough to bring GTR2’s force feedback closer to modern standards.

You will most likely have to edit your UserData PLR file to get the right feel of your force feedback.

The HQ Anniversary Patch provides new UI menus that give you access to more FFB tuning parameters than the default screens provided. They don’t provide access to the most important FFB tuning parameters, unfortunately. The only other method is, unfortunately, to edit the GTR2\UserData\User.PLR file.

So, for those reasons, see the SHO Competition FFB mod linked above.

Modern GTR2

You can think of Modern GTR2 as my setup specification for a baseline modern GTR2 experience. -Shovas

GTR2 holds up remarkably well in the features department but shows its age in the level of quality we now expect of those features. Some things can be improved like textures, visual effects, sounds, even AI and new and improved cars and tracks, themselves.

Original Tracks Updates

HD Gloves and Suits

8K Beautiful Skies

High Resolution Mirrors

Mirrors are low resolution in GTR2 with no way to fix in-game. No worries, just download High Resolution Mirrors by Speed1 and drop MIRROR.BMP in your GameData\Teams folder. That’s it.

You can also extract MIRROR.BMP from the HQ Anniversary Patch by GTR233. It’s a bit more work but they might be newer, and there’s a 1K and 2K version, but honestly I can’t see much of a difference.

Crew Chief GTR2 Enhancements Plugin

I consider Crew Chief and the GTR2 Enhancements Plugin that it comes with to be a critical part of a modern GTR2 experience.

Requires Steam GTR2 or HQ Anniversary Patch compatibility options

Crew Chief brings a voice spotter which the GTR2 Enhancement Plugin enables but the plugin also provides other great fixes and features like graphics flicker fixes, use-all-cores-by-default, borderless windowed mode, various crash case fixes, VR support, gearbox enhancements, and a lot more and a lot more coming from the sounds of it.

Click here for the GTR2 Enhancements Plugin homepage with the latest details.

See the full list of features below.

Download and Install

Click here to download from the Crew Chief homepage and it will come with the latest release of the GTR2 Enhancements Plugin. The download link is in the middle of the page (“Download CrewChief for PC”).

Install Crew Chief, run it, select GTR2 under the “Game” heading, and click Properties:

  • Set “GTR 2 install path (text)” to your GTR2 folder path
    • Something like “C:\Program Files (x86)\Steam\steamapps\common\GTR 2 – FIA GT Racing Game” but yours might be different
  • Set “GTR 2 launch exe (text)” to your GTR2.exe path and file name
    • Something like “C:\Program Files (x86)\Steam\steamapps\common\GTR 2 – FIA GT Racing Game\GTR2.exe” but yours might be different

Then you just click the Start Crew Chief button when you want to use it with GTR2.

You’ll know it’s working if you hear a voice when you get into the cockpit.

Features

As of October 6, 2022, Crew Chief and the GTR2 Enhancement Plugin enable and feature:

  • Crew Chief
    • Spotter with real voice call-outs for things like “car left/right”, time remaining, cars gaining from behind, etc. It’s extremely well done. Absolutely recommend downloading Crew Chief.

Custom HUD Overlays

Both SHO XD Style SimHub Overlays and the original XD Telemetry Overlays provide additional helpful HUD overlays that include things like Tyre Wear/Temps/Pressures, Leaderboard, and more.

Click here to download XD Telemetry Overlays (requires Disc GTR2.exe or HQ Anniversary Patch fixed GTR2.exe)

Here’s some screenshots to illustrate (click to view full size):

  • XD Telemetry Overlays

    XD Telemetry Overlays


And here’s a video to demonstrate SHO XD Style Telemetry Overlays:


Until recently, XD Telemetry Overlays was the de facto way to get tyre wear/temps/pressures and a leaderboard. It’s great and still provides exactly what you need but it also hasn’t been updated in a while, only provides a few overlays, and doesn’t work with the Steam GTR2.exe (not a problem if you use HQ Anniversary Patch which installs a compatible GTR2.exe).

The modern and up-to-date way to get add-on or custom overlays in sims is with SimHub. The SHO XD Style SimHub Overlays mod provides a collection of overlays reproducing the XD overlays, in the XD style, replacing original GTR2 HUD overlays, and adding new overlays.

Here’s a list of overlays included in SHO XD Style SimHub Overlays (as of June 2022):

  • Awareness Left/Right/Rear
  • Dash/Mini Dash/Mini Dash V(ertical)
  • Delta Bar
  • Lap Info
  • Leaderboard
  • Live Track Map
  • Pedals
  • Position Info
  • Radar
  • Relative Leaderboard
  • Splits/RSplits Info
  • Shift Light
  • Status Info
  • Tyres Temps/Pressures/Wear + Brake Temps + Oil/Water Temps

Repositioning Original XD Standings Box

Here’s an XD overlay tweak to the XD.INI file that repositions the Standings Box to top-left, to the right of the native Position dialog. This prevents the Standings Box from getting in the way of the rearview mirror. Here’s the tweak: StandingsPosX=370 and StandingsPosY=0. To reduce the number of entries in the Standings Box, so it takes up less space, set StandingsPlayersVisible=7. I find this improves the layout and frees up the screen for where you really want to look while you’re racing.

Repositioning Original XD Tire Temps (Motec) Box

I found the default (automatic) position of the XD Tire Temps (Motec) box covered the flags (on 1920×1080) that show up from time to time so here’s a list of alternative positions for 1920×1080 resolution using the HQ Anniverary Patch Power & Glory 3 (PNG3) HUD – Use these as examples for how to move them when using different HUDs.

  • PNG3 HUD: Top-left (covers flags), Scale=100, MotecPosX=auto (20?), MotecPosY=auto (50?)
  • PNG3 HUD: Bottom-right, Scale=100, MotecPosX=1670, MotecPosY=725
  • PNG3 HUD: Bottom-right, Scale=90, MotecPosX=1690, MotecPosY=700
  • PNG3 HUD: Bottom-right, Scale=80, MotecPosX=1720, MotecPosY=775
  • PNG3 HUD: Center-left, Scale=80, MotecPosX=550, MotecPosY=870
  • PNG3 HUD: Bottom-left, Scale=100, MotecPosX=20, MotecPosY=670
  • PNG3 HUD: Bottom-left, Scale=90, MotecPosX=20, MotecPosY=695
  • PNG3 HUD: Bottom-left, Scale=80, MotecPosX=20, MotecPosY=720

HQ Anniversary Patch

HQ Anniverary Patch is a go-to drop-in solution to modernize GTR2 with just one mod. I, personally, copy&paste my GTR2 folders so that I have Vanilla GTR2, Minimum GTR2, Modern GTR2, and HQ Anniversary Patch GTR2 installations that I can run separately whenever I wish.

Click here to download HQ Anniversary Patch

Notes:

  • There are 2 parts to download (as of June 2022)
  • Requires latest [7-zip.org 7zip] to extract. You could need to open the first archive in 7-zip and extract: 7-zip is smart enough to extract all parts at once.

Here’s the mod description:

This GTR2 HQ Anniversary PATCH represents 6 years of work (nearly 20 000 FILES!) and includes all the necessary MODS/PATCHES for GTR2 plus tons of HQ textures. There are 2 games in 1, first the default 2003-2004 game with stock cars and tracks which get only few textures updates, second the HQ Cars&Tracks (with “HQ” prefix in menu) which get ALL the fixes/patches, more HQ textures plus exclusive graphics (both 2D/3D) : indeed, my will is to keep original game untouched to avoid online mismatch on internet and to see all the work done so far in this HQ Anniversary Patch when you compare both.

Go ahead and get it. Don’t even think twice. It’s that’s good. If you want to keep your vanilla install then just copy&paste your GTR2 folder, install the mod, then run GTR2.exe whenever you want, and then you’ll have both vanilla and HQ versions.

In-game

Game Settings

Field of View (FOV)

GTR2’s default FOV (field of view) shows you a large amount of your cockpit but it’s not realistic and can be a disadvantage in terms of judging speed, distance, and general timing. You will almost certainly be faster with correct FOV because you’ll be better able to judge speed, distance and timing.

Need convincing? Try watching this classic Empty Box video on why you would adjust your field of view.

If you use HQ Anniversary Patch your FOVs will be updated for you, and you probably won’t need to change anything, but otherwise you can do so manually in the GTR2\UserData\defviews.cam file as described here.

If you find you need to, tweak the field of view somewhat wider than default.

As a good rule of thumb, you want your field of view to include your driver-side mirror and about half of your rear-view mirror.

For those with head tracking, such as TrackIR, Tobii, or VR, bring your FOV so taht you can see half of your driver-side mirror and half of your rear-view mirror.

Field of View (FOV) Calculators

The old projectimmersion.com fov calculator is sadly defunct but I'll keep the example here to give you a point of reference for whatever calculators remain, as they all put out the same values.

The Project Immersion.com FOV calculator is a handy site to calculate your correct FOV from the size of your monitors and how far away you sit. The “vFOV%” value it calculates a factor which should be applied against the default vFOV value in the GTR2\UserData\defviews.cam file: 

LocalCam=COCKPIT // Inside View
{
  Fov=(112.0, 62.0) // Change 62.0 to the vFOV% value
  ...
}

ProjectImmersion.com says my GTR2 vFOV% is 40% so that means I should change 62.0 to 40.0. Try it out. I adjusted mine from the suggested value. You probably will, too.

Note! Select Race 07, GTR EVO (vFOV%) from the FOV Type drop-down for use with GTR2.

Seating Position

While not as important as FOV, one thing I've found handy is setting FOV about right and then using seat adjustment to bring the seat forward until the bottom edge of my screen is about in the center of the wheel. In other words, I move in until I can see only the top half of the brand logo in the center of the wheel).

Combined with FOV, this gives a decently immersive cockpit field of view experience, in my opinion.

Wheel Rotation and Wheel Lock

You’re probably on 900+ degree wheel, like a G27, T300, ClubSport, or modern Direct Drive wheel, so when you get into the GTR2 GT-style cars it will feel like you’re driving a bus: You’ll feel like you need to turn the wheel more than should be needed to get the car to turn the right amount – This is a wheel rotation and wheel lock setting issue.

It’s probably best to set a 540degree wheel rotation in your wheel profiles for GTR2. Then, in-game, the default 15degree wheel lock will feel better, but if it doesn’t try 18-22 degree wheel lock, give or take a few degrees. Somewhere in that range will be a 540degree sweet spot.

GTR2’s native in-game wheel rotation is 240degrees. I now set my real wheel to 240degrees to experience the game as it was designed. This makes things like default steering locks, virtual wheel rotation, and general handling feel much more in-sync and cohesive.

Defviews.cam (Texture Quality, etc.)

I wasn’t able to notice a change using negative values so it may be that the default value (0.0) is the optimum value, here.

Higher quality textures can be made to load in at farther distances by decreasing MipmapLODBias in UserData\defviews.cam. The effect is most noticeable on cars when increasing above 0.0: Textures look blurrier at closer distances.

Mipmaps are supposed to be about higher or lower quality textures but to be honest the effect doesn’t look like loading in higher or lower quality textures, it just looks like textures becoming blurrier at a distance. Maybe it’s just hard to tell.

Performance

Improve Frame Rate by Making GTR2 Use More Cores For Better Performance

By enabling GTR2 to use all cores, you can significantly increase your FPS, perhaps by more than 2x. It's an absolute must.

The Crew Chief GTR2 Enhancements Plugin enables using all cores by default. Otherise, use the free Bill's Process Manager or the paid Process Lasso (I paid for it, I think it's worth it for other old games like GT Legends, Race 07, etc.).

There are other applications that do the same thing, too. Try a google for “window cpu affinity tool” if you’re looking for a different one.

How to use Process Lasso with GTR2:

  • Start Process Lasso
  • Click Options menu > “Configure default CPU affinities …”
    • Process name: GTR2.exe
    • CPUs: All
    • Click “Add to list” button
    • Click OK
  • Click Options menu > “Configure default CPU priorities”
    • Name match: GTR2.exe
    • Select “High” from the priority drop-down
    • Click “Add to list” button
    • Click OK
  • Start GTR2 and enjoy better performance!

Remember: Process Lasso must be running before you launch GTR2.

Note: Some have said more than two cores assigned to GTR2.exe doesn’t seem to make a difference. I’ve seen GTR2 use 4 cores, myself, but it certainly gets the biggest boost from 2, then less of an improvement as you add cores. I just enable them all for convenience.

Force Feedback (FFB)

SHO Competition FFB

Consider #RealFeel FFB before trying this.

See the earlier #Force Feedback Settings section.

SHO Competition FFB for GTR2 is a mod that crowd-sources wheel-specific FFB parameters.

Shovas Custom FFB Files (Obsolete)

Before I created SHO Competition FFB, for crowd-sourced wheel-specific FFB parameters, I published “Custom FFB Files”. I no longer recommend or support these as they have been far surpassed by SHO Competition FFB.

RealFeel FFB

I am increasingly leaning towards RealFeel FFB as the universal drop-in solution for GTR2 FFB as it requires less tuning, simplified global and per-car configuration, tyre-at-rest physcs, and potentially has better physics-to-ffb implementation vs original game FFB including SHO Competition FFB.

RealFeel FFB is enabled by Crew Chief GTR2 Enhancements Plugin by The Iron Wolf. I highly recommend it. -Shovas

Guidelines for Tuning GTR2 Force Feedback

  • Tune one FFB parameter at a time
  • Do NOT use Vsync or Frame rate capping
    • Frame rate matters to GTR2 FFB. The FFB update loop is tied to the frame rate so a 50fps FFB experience will feel differently than a 100fps FFB experience. The more FPS you have the better FFB will feel.
  • Change as little as possible to avoid variables throwing off your tuning
    • Save a race session and keep using it every time you exit and enter GTR2 after changing FFB parameters
    • Use the same track
    • Use the same car
    • Use the same setup – including things like tire types, pressures, etc.
  • Certain effects play off each other:
    • Grip Weight vs Grip Factor
      • Reducing/Increasing Grip Weight can Reduce/Increase the Grip Factor effect so you may need to make an opposite adjustment to Grip Factor. The opposite can also happen: Changing Grip Factor might require a need to adjust Grip Weight.
  • Use bi-section searching to tune FFB parameters to reliably dial in your settings and help avoid bias and false leads.

Force Feedback Tweaking Guide for Simbin Games by Julien Regnard

A helpful guide (plain text backup link) with a little bit better descriptions of FFB parameters in your PLR file.

Of special note in this file is the section at the end titled “3. Tweaking FFB parameters”. His baseline FFB PLR values are really educational and informative to experience and especially to use as a baseline to experiment with values one by one.

Please note, while I find the guide incredibly helpful, I find some of Julien’s advice counter-intuitive, at the least:

  • Friction vs Damper:
    • Julien recommends a negative Friction “to be sure that the wheel moves fast when required by the car movements” but the point of friction to simulate some of the drag on the steering column. Negative friction defeats that purpose, so I’m left confused. Maybe this makes sense on older/lesser wheels but I just can’t see how this makes sense on modern wheels. I ended up at zero or small positive values for friction.

Helpful Guide for Advanced Force Feedback Tweaking

Check out this guide, Force Feedback Tweaking Guide for SimBin Games, for helpful descriptions and tips for advanced force feedback tweaking using the UserData PLR files.

Pro Tip: What do the FFB Effects Levels mean?

  • Low: Steering + Grip
  • Medium: Adds Friction + Damper + Rumble strips
  • High: Adds Brake vibration
  • Full: Adds Throttle vibration + Steering vibration

Rumble Strips Pushing/Pulling the Wrong Way

I noticed rumble strips were pulling me off track instead of tending to push me back on track. Luckily, I noticed an FFB setting:

Update 2017-11-10: I believe I was wrong about the feel of this. I now feel there’s some legitimate drag to larger, more raised kerbs (eg. at Spa) and some kerbs lift your rear tire enough to lose grip on the backend thus acting like sliding on the backend and feeling like being “pulled” off the track. Consider reducing Spring and/or Fast Bump/Rebound to deal with this. My Pull Factor FFB setting is now the default 1.5.

  • FFB rumble strip pull factor=”-0.890625″ // How strongly wheel pulls right/left when running over a rumble strip. Suggested range: -1.5 to 1.5.
    • Looks like this should be negative: -1.50000
      • My bisection search: -1.5, -0.75, -1.125, -0.9375, -0.84375, -0.890625
    • Positive vs negative could be wheel dependent. So you’ll have to test to make sure.
    • You may want to tweak this value. It’s a little strong feeling for me.

The GTR2 Force Feedback Engineer

Inspired by the Project Cars 2 Race Engineer, which provides an in-game question and answer interface to solving car setup issues, I thought I’d document the same kind of thing for GTR2 from a Force Feedback perspective.

In GTR2, and probably most early SimBin titles, the most important Force Feedback tuning parameters are not exposed by in-game settings. These settings include Force Exponent, Grip Weight, Grip Factor, Friction Coefficient, and Damper Coefficient. You’ll need to edit your UserData\USER\ PLR file to change these settings.

Engineer: What’s the problem?

Driver: Well,

  • I can’t tell when I’m losing grip. The wheel doesn’t go light enough when I’m losing grip.
    • Increase Grip Weight
      • Increases Grip forces, which decreases Steering forces at the same time, which increases wheel weight loss due to grip loss and can help you identify when grip has been lost because the wheel feels lighter.
  • The wheel goes too light when I’m losing grip.
    • Decrease Grip Weight
      • Decreases Grip forces, which increases Steering forces at the same time, which reduces wheel weight loss due to grip loss and helps keep the wheel forces stronger.
  • The wheel feels loose or force feedback is weak on straights, in corners, everywhere in general.
    • Decrease Force Exponent
      • Compresses forces over a narrower range, so more total force, so that forces are compressed around center causing the wheel to feel tighter or forces to feel stronger.
  • The wheel feels tight/jittery around center on straights.
    • Increase Force Exponent
      • Evens out forces over a wider range, so less total force, so that forces are not all compressed around center causing high forces or spikes which you feel as tightness or jitteriness.
  • There’s too much centering spring feeling in the wheel.
    • Increase Force Exponent
      • Evens out forces over a wider ranger, so less total force, so that all combined forces do not cause too much force towards the center.
  • The wheel force feedback goes ‘numb’ during hard or high speed cornering. I can’t feel anything.
    • Increase Force Exponent
      • Evens out forces over a wider ranger, so less total force, so that all combined forces do not overwhelm the wheel and cause ‘clipping’ (ie. max force reached so can’t feel any more forces, it just feels dead) and this should allow forces, while somewhat weaker, to still be felt.
  • I can’t feel the road, such as bumps, lines, or contours.
    • Increase Grip Weight
      • Increases Grip forces which are affected by road bumps, lines, and contours, so your wheel will emphasize greater and lesser weight feel that help identify road feel through force feedback.
  • I can’t catch the car when the backend loses grip and slides out.
    • Increase Grip Weight
      • Increases Grip forces, which lowers Steering forces at the same time, which provides emphasized grip information through force feedback that should help you catch backend slides more easily.
    • Decrease Grip Factor
      • Decreases Grip forces from the front tires, which increases Grip forces from the rear tires at the same time, which provides emphasized rear grip information through force feedback that should help you catch backend slides more easily.
  • There’s not enough resistance when I turn the wheel, in general.
    • Increase Friction Coefficient
      • Increases constant friction forces so the wheel feels heavier to turn. Real steering columns have inherent friction so tuning friction can make it feel more realistic.
  • There’s too much resistance when I turn the wheel, in general.
    • Decrease Friction Coefficient
      • Decreases constant friction forces so that the wheel feels lighter to turn. Real steering columns have inherent friction so tuning friction can make it feel more realistic.
  • The wheel rotates too quickly during some forces, like there’s not enough resistance. It doesn’t behave like a real wheel.
    • Increase Damper Coefficient
      • Increases the fluid dampening applied to forces so it will spin up more slowly
  • The wheel rotates too slowly during some forces, like there’s too much resistance. It doesn’t behave like a real wheel.
    • Decrease Damper Coefficient
      • Decreases the fluid dampening applied to forces so the wheel will spin up more quickly.
  • Wheel forces feel like they’re clipping in high ffb strength scenarios but I’m not even at max FFB strength on the wheel.
    • Decrease Steer Force Output Max
      • Reduces the amount of strength applied to steering forces and frees up FFB strength headroom for road bumps preventing force clipping in high ffb strength scenarios like high speed corners.
      • This is known as ‘soft clipping’ where your wheel FFB strength has sufficient strength but the in-game calculations are overwhelming their own maximum FFB strength output. This results in numb steering forces taking up 100% of the in-game FFB output and providing no room for road bump forces which provide feeling on the road.
      • Caution: Damper and Friction will become increasingly apparent as you decrease Steer Force Output Max and you will want to adjust them accordingly.

TrackIR Head Tracking

TrackIR is a great step if you’re not yet willing to go to VR, like myself, and the good news is GTR2 supports it out of the box!

I find it works extremely well to achieve the ability to look around the cockpit, at your mirrors, and out your side-windows on a single screen. You should find slides easier to notice and correct as your head stays looking in the direction you want and your car rotates around you – as you would expect in real life. The added head movement also gives you a slight depth-perception improvement due to subtle angle-of-view changes as your car moves, your head moves, and bumps affect your cockpit movement.

Here are my TrackIR settings: The settings mainly try for 1:1 head movement while looking at your cockpit and mirrors, and then accelerates so that you can look out your side-windows without straining your neck too far.

TrackIR Fix for Camera Uphill/Downhill Extreme Angles

TrackIR users probably want to set Video options World Movement to 1% (not zero) to stabilize the vertical angle of the cockpit camera to the angle of the car so that when you’re going up or down a steep hill you don’t lose sight of the bonnet of your car looking too far up while going downhill or end up looking at your feet looking too far down going uphill.

Zero World Movement is lock-to-horizon, I guess, and to me that doesn’t work for TrackIR users.

World Movement greater than 1% causes your cockpit camera to stabilize with the car angle but the “world” (ie. what you see of the car and the track) ends up bouncing around so a high World Movement number isn’t great, either.

So 1% seems to minimize ‘world shake’ and stabilize the cockpit camera to help when you’re going up and down hills.

Modders

Here's just some of the modders I know of or interacted with over the years.

Mods

Tip: Use VirusTotal.com when downloading files to quickly and automatically scan a file with all (or at least most) of the anti-virus and anti-malware solutions out there.

Race Department.com is one of the best, cleanest, and most professional of the sim racing sites I know of that also host downloads section. I highly recommend registering for ~$3/month or ~$15/year for unlimited downloads and removing all ads, amongst a host of other perks.

Other sites that curate mods and other downloads include eSport-Racing.de, Koelschbierbude.de, and Festbierbude (GTR2 Power & Glory Mod Focused).

Trackaholics and European Endurance Center have dedicated Release forums where modders regularly post new and updated releases.

Check out the #Community sites for more details.

Mod Package Managers

Mod package managers enable one-click install and uninstall operations for mods with the same folder structure as the GTR2 folder. Most modders do this but if not just re-create their archive with the proper folder structure and it will work.

Running Mods

Generally speaking, the process of adding cars, tracks, or mods usually just involves a download and then copy&pasting the files into your GTR2 folder. Usually, it’s pretty straight-forward, although sometimes authors don’t use a consistent folder structure and you may have to figure out where files go (ex. track mods often give you the files but not the folder structure – track mod files should go in GTR2\GameData\Locations\FolderName).

Modding

In 2024, the best places to get into GTR2 modding are probably Race Department, Trackaholics, and European Endurance Center.

How Tag Filters and Classes Tags Work

These are the Game Filter, Selection Filter, and AI Filters you can find in some GDB files and Classes tags you can find in CAR files.

  • Tag Filters
    • Example: OR: Gr2 AND: PG1958, PG1959, PG1960, PG1961

      • AND Boolean Operator
        • Follow with a comma-separated list
        • Follow list with a space to start a new boolean clause
      • OR Boolean Operator: Follow with a comma-separated list

How to Practice, Qualify, and Race against AI

My best and most recent tips for dealing with AI will now be in the SHO Competition AI mod README file.

You don’t need to install the mod if you just want tips on how to qualify and how to race against AI. Just read the README file section on racing the AI.

Custom Daylight Acceleration

Edit your UserData PLR file and change the Time Scale Factor parameter to any value between 1 and 600 where 1 is real-time and >1 accelerates time.

For example, I chose Time Scale Factor=”24″ to experience a full day-night cycle in a 1 hour race.

More recently, I’ve been using Time Scale Factor=”12″ to experience half a day-night cycle in a 1 hour race. I chose this to have some daylight transition but not too much in my usual 20min races.

Note! 24 Hour races do not use Time Scale Factor. You can set a race length when setting up a 24 Hour race and GTR2 will automatically set the time scale. For example, you can setup a 24 Hour race with a 1 hour race length and you will still experience a 24 hour day-night cycle.

Hint: Find your GTR2 folder and you’ll see your UserData\Player\Player.PLR file. Edit this file. Mine is “G:\SteamLibrary\steamapps\common\GTR 2 – FIA GT Racing Game\UserData\Shovas\Shovas.PLR” but your location and PLR folder and file name will be different.

Changeable Rain

Changeable seems to bias rainfall towards Track’s GDB Average Rain parameter. In other words, a track like Donington or Spa may have more sessions with rain than Dubai or Valencia.

This seems to apply for Temperature as well where Dubai will be routinely much hotter than Donington although this does not seem to be an editable file but baked into the track so you’d need an editor to change this, I guess(?).

Resources

  • GTR Engineers Handbook – The official GTR Setup Guide (Backup; HTML)
    • “The official GTR Engineer’s Handbook, which is hard to find on the internet (and not included with the game). It was made for the first GTR game title by Simbin in 2004, but it also applies to the sequel.”
    • “Combined with the GTR2 Car-Owner’s Manual, it’s a must have for those who use GTR2’s original cars. A great source of knowledge for GTR2 users, as it provides important information as a setup guide.”
  • GTR2 Car-Owner’s Manual – Extensive details on the car specs, tyre character, power graphs, etc (Backup);
  • “Along with the GTR Engineers Handbook, this manual is a must have for those who use GTR2’s original cars. It has all extensive data on every single car specs, such as tyre characteristics, ideal temps and pressures, power graphs, transmission, aerodynamics, weight balance, etc, etc.”

Trivia

Did You Know?

GTR2 is deeper than you might think: This is a section for trivia about the things you might not know even if you’ve been using GTR2 for a long time.

  • Setting Changeable Rainfall Enables More Realistic Weather
    • Requires Crew Chief GTR2 Enhancements Plugin
    • Setting Rainfall to None will use a clear, sunny day and the temperature will progress from 20C to 30C every session, every race, every time. Set Rainfall to Changeable to enable more realistic weather based on the location. Eg. Overcast at Donington, Sunny at Barcelona, etc. These are based on weather probabilities for the geographic location of the track.
  • GTR2 suports 180hz+ FFB refresh rate
    • GTR2’s FFB update loop is tied to your frame rate. So, the more FPS you get the more refined your FFB experience will be. Disable vsync to start. Then, allow GTR2 to use all CPU cores by using the free Bill’s Process Manager or nagware Process Lasso (I ended up purchasing this and can recommend). If you’re still not satisfied, SHO Competition FFB provides crowdsourced FFB profiles for many wheels and reviewers say it really brings GTR2 FFB to life.
  • GTR2 has fully animated feet
    • The right foot moves in and out on the gas pedal as you would expect. The left foot brakes but it will also move over to the clutch and go in and out there. Here’s one I didn’t expect, when slowing down for a corner the right foot moves over to the brake pedal while the left foot stays on the clutch…for heel and toe I guess?
  • GTR2 can use external sounds in the cockpit
    • External sounds often sound better to me than the muffled normal cockpit sounds. Edit your PLR and set: Only External Engine Sounds=”1″ // Always use external engine sounds regardless of current view
  • GTR2 is hard-wired to 240 degrees ffb wheel rotation
    • So unless you have a 240deg physical wheel the in-game animation won’t match your physical wheel. Find out why you might want to consider setting your wheel to 240deg besides getting matching animation over on this Race Department post.
  • When selecting opponents and the number turns red, it means the game has run out of unique cars and it will start duplicating cars.
    • You normally have enough cars that you’ll still get a good race. The only situation might be in cases like the BMW M3 GTR where you only have two unique cars, and so only two unique AI, which means there might not be enough variety in the field to have a realistic feeling race.

Quick Tips

These are quick tips that can be said in simple ways. More involved tips can be found in the Tips and Tricks section.

  • Faster Time Acceleration
    • In the garage in a race session, time acceleration will go faster on the Timing screen. So, if you’re trying to time accelerate to see AI lap times and/or rubber in the track, try using the Timing screen instead of the cockpit feed screen.
  • Timing Screen Laptimes Details
    • In the garage in the Timing tab, right-clicking on a driver will show their individual laptime details.
  • Choose Your Own Starting Position
    • Unselecting all qualifying sessions, when setting up a race, will enable the Grid Position selector so you can manually select where you want to be on the grid.

Tips and Tricks

iRacing-like Brake Sensitivity for Potentiometer Pedals (eg. G27)

If you’re used to iRacing and have potentiometer based pedals, like G27 pedals, you’re probably used to an iRacing default Brake Force Factor of 1.80x. In GTR2, and many other sims, brake sensitivity is linear and won’t feel like iRacing braking. You can achieve iRacing-like braking sensitivity by adjusting Brake Sensitivity in the in-game control options and lowering the value. Personally, based on my measurements, somewhere between 0-25% brake sensitivity is similar to iRacing braking progression judging by the in-game brake meter. Give it a try and use what you like best.

Note: I’m still testing, myself. It’s somewhere less than 50%, though, as 50% is linear in SimBin games.

If you don’t have potentiometer pedals, you may or may not want to adjust the brake sensitivity. I’ll assume you’re an advanced user, if you have these higher-end pedals, and you know what you want from them.

Use Auto-Clutch With Paddle Shifters

Use auto-clutch, available in the Realism settings, when making use of paddle shifters, otherwise shifts will be abrupt and cause wheel spin on up-shifting or lock-up on down-shifting.

Disable Auto-pit and AI Control

By default, your car will enter “auto pit” mode when you enter and exit the pits meaning AI controls your car until you exit the pits. Being used to driving the cars in pits, myself, I disable this:

  • Edit your UserData PLR file
  • Under “[ DRIVING AIDS ]” set:
    • Autopit=”0″
    • No AI Control=”1″ // AI never has control over car (except autopit)

Improve your driving by Turning up Tire Scrub and Tire Skid volume

Go ahead, turn up tire scrub and tire skin in the audio options and I think you’ll find it’s one more piece of information you can use to aid your driving around the track. I always find it helpful to match up the audio of slips and slides with the visuals and the force feedback.

Don’t skip sessions (causes AI bug). Use Time Acceleration, instead.

Don’t skip sessions. Use Time Acceleration.

Skipping can result in AI not setting laptimes and this results in randomly placed AI on the grid in addition to AI laptimes that don’t match the AI difficulty level set if you had run the session to completion instead of skipping.

Always time accelerate, never skip.

Use the Timing screen to make Time Acceleration go even faster.

Use High Shadows (Not Full Shadows) Option To Avoid Dark Screen Driving Through Shadows

In some mod cars, driving through shadows will make the entire car interior dark, too dark, including the windshield which should be the normal outside brightness.

Use High Shadows instead of Full to fix this. With High it acts as though you haven’t driven through a shadowed area at all, which isn’t great, but it’s a better alternative.

Steam GTR2 vs Disc GTR2

This is a list of differences between the Steam version of GTR2 and the Disc version of GTR2, at least so far as I am aware.

  • Steam
    • EXE and DLLs: Various EXE and DLL files are different which produce the differences we see in-game.
    • Missing or Grayed Out Cars: Ferraris and Porsches are grayed out on track and not available in the menus. See fix here.
    • Hockenheim GP Slow AI: AI cars drive around track at what appears to be pit limiter speed. See fix here.
    • Hockenheim Short Uncounted Laps: Laps are counted. I don’t think there’s a fix available but watch here.
  • Disc
    • No notes yet

How To Make Disc GTR2 From Steam GTR2

Starting from a clean and up-to-date Steam GTR2 folder:

  • Copy over Disc EXE and DLLs files

That should bring an updated Steam GTR2 up to an up-to-date version 1.1.0.0 Disc GTR2. There are some other inconsequential file differences (see screenshots above) but that should do it.

Caution: This is a work in progress and may not be completely correct but I’ll keep updating it as I find out more.

Known Issues

Skipping Qualifying Results In Random Grid Positions And Unrealistically Fast AI Lap Times

Don't skip. Use time acceleration.

There is an issue where skipping the rest of your qualifying session will result in the AI having faster lap times than they should have. Additionally, when starting a race, starting positions may appear to be randomly set instead of using qualifying times.

Use Time Acceleration to get the end of qualifying more quickly. Use the Timing screen to make Time Acceleration go even faster.

The Leader’s Advantage AI Bug

Update 2023-07-29: This has to do with the Composure parameter in Talent RCD files. I have experimented with this to good effect in the SHO Competition FFB mod over at Race Department.

When the player is ahead of the AI, the AI have tendency to go slower than if they were ahead of the player. This can happen even when qualifying suggests competitive timings: Even if you start further back in the grid, if you can manage to get out in front then the AI have a tendency to slow down.

Also, if you start further back in the grid, try to make up as much ground as possible or else the AIs ahead of you, especially top 3 or so, will tend to be uncatchable for the rest of the race.

I guess the ‘solution’ here is to find out where qualifying place results in a competitive race for you. For example, I try to qualifying top 3-6, at least, and make sure I stay up with the faster cars off the start.

Swingman Rear View Takes A Long Time To Orient Above Car

Edit UserData\defviews.cam and, in the LocalCam=SWINGMAN section, increase the first parameter of the OrientationRate.

For example, I use OrientationRate=(9.30000, 2.43750000, 0.000000). This ensures that the camera moves quickly from being about bumper level to being above and behind the car as you would probably expect from other video games with external, rear racing views.

I have confirmed that the first two parameters of OrientationRate are Pitch (up/down) and Yaw (left/right). That is, the camera moves in relation to the center-point of the car.

I assume the third parameter is Roll (left/right rotation) and it’s disabled by default because flipping the camera upside-down when your car crashes would be counter-intuitive but I haven’t found an easy way to confirm this.

Swingman Rear View Follows Too Narrowly Behind Car

The other tweak to OrientationRate=(9.30000, 2.43750000, 0.000000) I do is the second parameter (Yaw) which I set to 2.43750000.

Decreasing Yaw rate allows the camera to lag behind the angle of the car just a bit more than normal so that going around corners you see a bit more of the car. I kinda wanted to show off the cars more like in Forza Horizon, etc.

Steam Comment about manually fixing issues

How to fix everything, restore removed content and some other things.

Right click on these files, click "Properties" and then "Compatibility" tab.

GTR2.exe - Run as administrator

2 - Navigate to offset "0026CD00" or press CTRL+F and search for the text string "pan"

Replace everything with "FF FF FF", skipping only the zeros, like this: "FF FF FF 00 00 FF FF FF"

You'll end at offset "0026CF80"

4 - Save and exit

Fix Invisible MoTeC

1 - In "GTR2Config.exe", make sure you set compatibility with Windows XP (SP 3) and is running as Administrator
2 - Click to play the game and then click in "Video Options" to set your Resolution and 32 bit

Note: If you already configured your video before following these steps, you'll need to configure again. That's because the GTR2Config.exe can't detect 32 bit if it's not in compatibility mode, even if it's showing 32 bit in the config screen.

Fix Arms in Rearview Mirror

1 - Go to this folder: ..\SteamApps\common\GTR 2 - FIA GT Racing Game\UserData\YourName
2 - Open "YourName.PLR" with any text editor
3 - Press CTRL+F and type "Rearview Front Clip"
4 - Change the value to "4.00000"

Increase Game Performance

1 - Start the game
2 - Press ALT+TAB
3 - Press CTRL+ALT+DEL to open the Task Manager and select "Details" tab

5 - Check "All Processors" and click OK
Fix Playtime Count
1 - Start the game
2 - sudo.exe will be executed and the game will start
3 - Exit the game
4 - Start the game again
Unlock All Tracks
1 - Open Notepad and click "Save As..."
2 - While in the save screen, go to this folder: ..\SteamApps\common\GTR 2 - FIA GT Racing Game
3 - Change "Save as type:" to All Files*
4 - Name the file "SDNDTG.DYN" and save

* VERY IMPORTANT

You NEED to select "All Files", otherwise the file will be saved as "SDNDTG.DYN.txt"

Easier AI in Simulation Difficulty

1 - Go to this folder: ..\SteamApps\common\GTR 2 - FIA GT Racing Game\GameData
2 - Open "Settings.ddb" with any text editor
3 - Press CTRL+F and type "Professional"
4 - Change "AIStrength" to 80
5 - Change "AIAggression" to 0.70

Now you can change the Strength from 80% to 120% and the Aggression from Timid to Psychotic.

Troubleshooting

Enable Debug Tracing

  • Launch GTR2 with -trace=1000
    • For Steam, right-click your game in your Library
    • Click Set Launch Options button
    • Add -trace=1000 in the text box
  • If a crash happens then check UserData\Log\trace.txt
    • Errors are likely near the end of the file. Google for the error message and you’ll likely find some tips to help fix it.

Crashes Loading Tracks

Try uninstalling previously installed mods and see if the problem happens.

To make this a little easier, make a backup of your GTR2 folder before you install new mods so you can rollback easier just by renaming folders.

This can also be related to large mods that need a lot of memory: So use the 4GB Patch mentioned above.

Black Screen Driver Stopped Responding Freezes

Update: This was due to an (unknown to me) bad video card and replacing the video card solved the problem.

If you experience graphics related crashes, such as ‘driver stopped responding’ black-screen freezes:

  • Try using DirectX 8, not Auto or 9 in GTR2Config.exe. This “solved” these types of crashes for me on Windows 7 (NVIDIA 980 TI).
