    Looks like Khronos are stalled on transform feedback though and they didn't explain what's slowing things down.

        OpenGL has transform feedback feature, similar to stream output in DirectX. Vulkan doesn't have it, and implementing it effectively isn't possible without spec and driver support. That makes projects like DXVK miss this feature.

          Is it used in some games? Do those games not work with dxvk because of this? Or do they run slower because there is a software fallback?
