Not a vkd3d bug, you need the native d3dcompiler_47 library.
Note that there are issues with vkd3d with this game, but we're aware of those.
@doitsujin, @aeikum, @HansKristian-Work do you know when we can expect this native d3dcompiler_47 library out of the box in Proton?

Software information
The game doesn't start when
VKD3D_FEATURE_LEVEL=12_0 %command%is set and when isn't.The launcher starts.
This is a game with the smallest FPS number I have so I set the low preset as I play on notebook and as results are very weak:
I decided to test it with vkd3d as there is an option to enable DX12 in the settings but it doesn't start.
