PROTON_NO_D3D11=1 %command%
Some pre-rendered cutscenes looked a bit off
Run the game with this command setting:
PROTON_NO_D3D11=1 %command%
Without this, the game crashed on launch.

WINE_CPU_TOPOLOGY=4:0,1,2,3 PROTON_NO_D3D11=1 %command%
Could not start the game without the WINE_CPU_TOPOLOGY changes with the new 5950 CPU.
PROTON_DO_D3D11=1 %command%
There was some low FPS during large explosions not sure if its just the age of the game but it did go down to 30 FPS from usually 100-200+ FPS.
Multiplayer works, skirmishes work, tutorial mission works, initial single player mission is borked.
Skirmishes worked fine, non in-game cut-scenes loaded, tutorial mission ran flawlessly , but initial soviet assault single player mission though did not load scripted in-game cut-scenes and/or single player assets required to play single player.

Ran with the launch option "PROTON_NO_D3D11=1 %command%" Performance is lower than I'd expect on my system. Lowering physics to low helped this somewhat.
