Tuning AI Performance For Starting From The Rear
- Session Setup:
  - AI: 100%
  - Rainfall 0%
    - Once dialed in, then you can enable Rainfall or Real Weather
  - Watch laptimes at least 15min
- Tuning AI Practice For Racing From Last Place
  - Practice Setup: Minimal fuel, medium tyres
  - You will be watching Practice laptimes for tuning this
  - If AI are not fast enough even at 120, or not slow enough even at 80, then you'll have to adjust Worst/Mid/BestAdjust in Location AIW files
  - For top 10 competitiveness, adjust AI Difficulty until your best laptime falls around the top 10 AI best lap times
    - Ideally, your best laptime should fall within the range of positions 10-12's best laptimes
    - You will be competing for the top 5-10 but probably not the top 5
    - If you want to compete for top 5 or top 3 then aim for your best laptime to fall closer to the front positions' best laptimes
Tuning AI Parameters That Influence AI Performance
- Notes:
  - This is not about finding the right AI Difficulty for, it's about dialing in AI parameters influencing AI performance
    - That's why Qualifying is done with 0% Rainfall
    - Once dialed in, then you can enable Rainfall or Real Weather
  - AI definitely perform differently if you qualify vs not and if you race with them vs quitting out and watching the timing screen
    - To get the most accurate AI performance, you have to be racing live with them
    - One exception: Start a session, put in a few good laps, then quit to Timing screen and they should race up to roughly your performance, and perhaps a bit above it
- Session Setup:
  - AI: 100%
  - Rainfall 0%
  - Watch laptimes at least 15min
- Tuning AI Qualifying
  - Caution: Tuning AI Qualifying performance is only necessary if you can't adjust AI Difficulty enough to get a satisfactory grid position (ie. you're too slow at AI 80 or you're too fast at AI 120)
  - Reminder: Do NOT skip Qualifying to the end. Use Time Acceleration instead.
  - Qualifying setup: Minimal fuel, soft tyres
  - You will be watching Qualifying laptimes for tuning this
  - Tune up/down Location AIW QualRatio until your Qualifying laptime falls in the middle of AI Qualifying laptimes (at AI 100%)
  - You should use a Qualifying setup ie. minimal fuel and soft tyres
- Tuning AI Race
  - Reminder: Do NOT skip Qualifying to the end. Use Time Acceleration instead.
  - Race setup: Laps-appropriate fuel, medium tyres
  - You will be watching Race laptimes for tuning this
  - To watch Race laptimes, start the race then quit to the garage and go to the Timing screen
  - Tune up/down Location AIW RaceRatio until your Qualifying laptime roughly matches the AI laptime for your Qualifying position

Description

SHO Competition AI is a GTR2 mod for original content cars and tracks that aims to improve the racing experience by creating greater racing immersion and realism by improving AI driver performance.

Please see "README SHO Competition AI.txt" as it contains helpful details on install/uninstall, tips, questions, known/open issues, testing notes, changes, and development notes. You might be reading this file right now: I've included this note here for easy copy&paste to places like Race Department download descriptions

Goals

- [Fix Stock AI Flaws] Improving obvious AI flaws on-track such as early braking, slow cornering, bad starts/first corners/first laps, and unrealistic crashes or collisions that all result in race performances that don't accurately represent qualifying performances

- [Improve Qualifying vs Race Performance] Furthermore, race performance should more closely reflect qualifying performance. With original GTR2 AI, you could start from the back of the field and win quite easily. Instead, the aim here is to ensure you have good, hard racing battles with opponents that qualified with similar laptimes. As such, if you qualify top 5 you might have a chance to win, but if you qualify top 10, it should be very difficult to win outright. That's just realistic. Again, the upside is good, hard battling with AI you are competitive against.

- [Keep Unique AI Personalities] Maintain original AI personalities and relative performance levels as much as possible to keep AI varied and interesting and allow rivalries to form between player and closely matched AI

What does SHO stand for?

SHO is the first three letters of my username (Shovas) but also happens to be an acronym used by Ford, which stands for "Super High Output", so I feel is an appropriately fun acronym for a sim racing mod :)

Why is it called "Competition"?

The aim of my improvements is always to improve the experience for a competition context, like racing real humans or racing AI, as opposed to say just hot-lapping. It's hard racing where you really have to have the best simulation to really raise the immersion and experience. That means my changes might feel better or worse for some depending on what you want but I'm always trying to be better in "competition", hence the name.

I think this provides clarity and is a nice compromise that maintains modding freedom while protecting the people that made them from losing credit to their work and against people who would cut out authors from profit from copying it.
