Firstly I started a game with this launch options: PROTON_NO_D3D11=1 PROTON_NO_ESYNC=1 %command% I had few issues during menus or game itself (shuttering, slowdowns, game quits on menus, exceptions during entering areas). All graphic settings set to lowest possible (or disable if possible), DX9 (game doesn't run on DX11, exception appears on game start). Then I used this launch options (taken from comments here): PROTON_NO_D3D11=1 PROTON_NO_ESYNC=1 %command% --waitforpreload --nologo --nodx9ex --gc2 Bingo, no more issues, any! Game runs flawlessly. I'm recommending this launch options (all graphic settings still set to lowest possible or disabled at all, DX9 used).
