you have to remember that proton is translating Windows software to Linux while you play so the fact that it works at all is pretty great, but of course it’s not a great experience you’ve had!
Have you tried experimental proton versions in the compatibility settings? Also do you have the proprietary nvidia drivers?
Frankly Linux, especially gaming, is not ready without plenty of command-line foo







translating! not emulating!!! (not sure what the appropriate word is)
