Fix Lag on Linux
If you experience lag or slowness on some parts of the game, it may be due to Steam defaulting to using DXVK, which at least on my hardware causes some issues.
To fix this add the following Launch Option to the game:
- PROTON_USE_WINED3D=1 %command%
That way it uses WineD3D with OpenGL instead, which works without any issues for this game.
