I had this game on Steam before it was removed from the store and installed it from there and it ran fine without forcing usage of the Steam Play compatility tool. It also worked with Proton-9.0-4, Proton Experimental and GE-Proton9-25.

Multiplayer works fine and was able to play games. Didn't have any issues with anticheat, it just showed that it was installing in the Steam loading screen on first launch.
