Hello @naoliv, Proton uses DXVK to translate DirectX 11 to Vulkan, which your video card does not support.

You could try using PROTON_USE_WINED3D=1 %command% in the game's launch options to tell Proton to use the DirectX 11 to OpenGL render path or alternatively, you could try -force-glcore to tell Unity 5.4 to use OpenGL.

I didn't know that, I am sorry.
It indeed did run with PROTON_USE_WINED3D=1 %command%
Probably this issue should be closed then?
Thanks!

Or maybe convert it to a feature request: if the video card doesn't support Vulkan, probably Proton should fallback to OpenGL.

[kisak-valve]

An automatic fallback was previously discussed on #1749, which concluded with #1749 (comment).

Understood. Thanks again!
