If by AC you mean Assetto Corsa, it works, you just have to follow a guide (it’s easy, you have to remove the Proton data for the game from Steam, then install the older Proton version, run the game with this older version until it crashes, then switch to new version of Proton and run it again. It will install required dependencies and will run fine, even my old G25 steering wheel worked without problems)
