Without tinkering, the camera didn't pan to the extreme right side of a room. With only Proton Experimental, the game often wouldn't return to full speed after you slowed down time. The game wouldn't start with the "PROTON_NO_D3D11=1 %command%" launch option. With "PROTON_USE_WINED3D11=1 %command%" the game ran, but my computer would sometimes spontaneously drop to the lock screen or go to sleep. With no forced compatibility and the "unset LC_ALL && PROTON_USE_WINED3D=1 MESA_GL_VERSION_OVERRIDE=3.3COMPAT %command%" launch options the game runs flawlessly.
