With the latest patch (2.02) and VKD3D_FEATURE_LEVEL=12_2, the game crashes right away during the intro video. All is fine, if I set VKD3D_FEATURE_LEVEL=12_1 instead.

This is not surprising. 12_2 forces ray tracing to be enabled, but without VKD3D_CONFIG=dxr, you get errors:

With VKD3D_CONFIG=dxr, it boots just fine.

Why are you even forcing FL 12.2? It is a gross hack to do that, and only intended for debugging or workarounds.

The game offers ray tracing graphics options only when forcing that specific Feature level. My 6950 XT supports raytracing (in theory, RADV support is still a bit behind the curve), so I wanted to try it out. Thanks for the tip with additionally setting VKD3D_CONFIG=dxr it now starts up correctly. This somehow used to work without specifying that additional option with an earlier game version though (with 2.00).
