I run many games using steam proton as well. I tried the method you described but it didn’t work for me. Wine provides a similar approach to emulating Windows programs, allowing windows games to run on Linux systems, I finally managed to get it running using Wine, but the experience wasn’t great. T he game was quite broken and far from playable.
Viewing post in There are plans to launch a Linux version?
Wine is garbage and sucks in running anything in general.
If your game wont launch at all when trying Proton, try to:
- Different Proton versions (not actual versions, but stuff like latest version, "hotfix", "experimental", and so on)
- Move the game files to your OS partition (yes, that indeed may work, you don't even need to change your Proton version)
