Won't start
PROTON_USE_WINED3D11=1 %command%
Used several versions: Experiemental, 8.0-3, GE-8-13, 7.0-6, 6.3-8 | all versions same result - crashes on startup

Proton-6.13-GE-1 GloriousEggroll
Proton-6.13-GE-1
Everything works fine except that when a mission is complete, the game exits back to the menu with all progress lost.
Right after a battle is won, the game exits back to the menu with all progress lost.
The overall game experience is enjoyable. The game takes longer to launch the first time but it becomes faster afterwards.
Added PROTON_USE_WINED3D11=1 %command% to launch parameters, otherwise the game won't start.
Right click didn't work for a couple of seconds after a match is started.
The game won't close properly, you need to kill the process but the game save is not corrupted by it.
with the latest proton version works out of the box no need to input any PROTON variables. played half an hour didn't see any bugs.

I added this to Launchparameters: PROTON_USE_WINED3D=1 %command% , otherwise the units are invisible. Tested menu ("map") and Gameplay against KI (Missions and Boris Neural KI); Loading times are a bit longer as on Windows; Gameplay and graphics were similar to Windows, no performance/graphic issues detected; Crashes when I exit the game but has no negative effect on the game process/save status

To make units visible add launch option: PROTON_USE_WINED3D11=1 %command%
