Any proton configuration isn't working for me, so I had to use "native mod loader" (i don't remember how it is called), and the game works fine, there are only 2 issues, with mouse and textures, but they don't make the game unplayabe, since im playing it on linux it works better than on windows (i have like +50 fps, and they are really stable), and what can i say?... its so stable, and i enjoy playing it :D
