I'd like to play with some friends but we don't have enough windows computers between us, so I'd like to get this game running on a spare linux computer via proton. I've tried the launch flag "PROTON_USE_WINED3D11=1 %command%" based on a recommendation from ProtonDB, and a few different versions of proton, but the game just isn't launching for me. Has anyone else tried this and gotten it to work? Supposedly some people have gotten this game running perfectly through this method but I have no idea how to make that happen.

In case it's relevant, I'm using Linux Mint
