@VVZ я точно не уверен, и сейчас нет возможности проверить, но попробуй в файле "документы/iracing/app.ini" покрутить вот эти параметры:
DriverHeadHorizon=0.000000 ; Percent to allow the drivers head to stay level with the horizon when the car tilts.
DriverHeadNoPitch=0.000000 ; Percent to allow the drivers head to stay level with the horizon when the car pitches.
DriverHeadWobble=0.000000 ; Percent to allow the drivers head to wobble when going over bumps.
DriverRotateHead=0.000000 ; Percent to rotate drivers head with slip angle. 0 to 1 with 1 being 100%
