Look up protondb for game compatibility. Arc raiders is marked as running perfectly fine, but plenty of multiplayer games with invasive client side anti cheats such as Fortnite or Genjin Impact do not run. If you depend on such games it's best not to switch, any privacy concern you may have with Windows is gone with those games running literal rootkits on your PC anyway.

I've been running Linux for gaming for well over 15 years and have not missed much in the last 5 or so. There's way too many games out there to play that do run on Linux even if unemployed and have the time to dedicate it as your sole hobby.
