It shows a message "DX12 is not supported on your system. Try running without the -dx12 or -d3d12 command line argument." I also tryed change proton version, pass PROTON_USE_WINED3D=1 and PROTON_USE_WINED3D11=1 both without success. In the former scenario, I was able to see the intro, however the game crashes as soon as the intro finishes.

I read somewhere to run the game with Windows 10 compability mode. I've actually tried with: protontricks $STEAM_SIX_DAYS win10

But I got:
