I read that it doesn’t work now, and you’re using lutris.
Have you tried Heroic (appimage) and Proton-GE?
Also, the expansion (phantom liberty) has DRM, so you won’t be able to run it from GOG just yet (there are workarounds like installing gog galaxy on wine, or using comet). First try to get ray tracing running without the expansion
Try setting
VKD3D_CONFIG=dxr
as a launch argument for the game
