Symptoms

Vulkan render for unknown reasons slower than DX12 render in 10 times. It means if I have with DX12 100FPS then on same scene with Vulkan I have only 10FPS.

Reproduction

Select "Start Vulkan" in the game launcher. And watch on FPS during game play.

Same problem here, with EGS copy of it. Happens with both Valve's Proton builds and Wine builds like Wine GE. Vulkan renderer is very slow. Just not 10X but 3X. AMD 7900XTX+ Mesa 23.3.2

I have asked around some folks too ( since EGS recently gave away that game ) and symptoms are:

Nvidia straight out crashes with Vulkan.
AMD works ( both RADV and AMDVLK ) but has that huge perf gap. On Windows both renderer options runs equally well.

WINEDEBUG=+vulkan and PROTON_LOG=+vulkan outputs ( Proton one is from Steam copy from @Blisto91 whom can repro the issue with Steam copy ):
