Hi, for cars that will be raced by AI is there a methodology to correctly set the AI level grip usage for racing with the player ? For instance if I want to do a custom 1995 mod from F1asr 412t2, with the 0.97 value from the original PLR file for corner grip, at 90-92 percent of difficulty the AI at max speed is able to beat the pole time from 96 at Albert Park. Unrealistic. Is there any other method than setting the difficulty at 100 percent and adjust the AI grip corner level untill they'll do the same time as in reality? Thanks
There are three difficulties that cascade the accuracy: Matching player cornering speeds with default setup. Optimal AIW. Matching real life lap times. If the mod's tires are inaccurate for the player, then 1 & 2 are all that you can achieve. Once 1 is achieved, if the AI are slow, then you can train the AI to be faster (I know, not your problem in this case). Once 2 is achieved, then you can tinker to match real life lap times, but you have to know or trust that the aerodynamics, engine power, and track all reasonably accurate... if you tune the mod's default setup for just one track, odds are it won't be right for other tracks, particularly when aerodynamics are adjustable! Overall, though, the quickest route to achieving your goal is adjusting the AI grip as you suggest.
Honestly, when the AI drivers are too fast respect the real laptimes in a track, one should pay attention to tbc file ( AI tyre file ), since tyres may do a lot of difference in performances of cars ( in this case, drivers ). Therefore, giving that AI drivers are using the same car setup, the first adjustment to equalize human and AI driver performances is in the grip of tbc tyres. ( lat-long grip values ). Tbc tyres should be also with the same dimensions of human tyres ( tgm ). For this purpose, there is the great online RF2 tool by Redapg. Then, you should also edit ( if needed ) the Rolling resistance of tbc ( to obtain exactly the same max speed between AI driver and human ). Finally, there is still in TBC an option about tyre grip percentage at the bottom of tbc file. So….HDV AI corner grip is maybe the last setting needed, I think
