Vkd3d-proton does support gpl for some edge cases already. Pipeline compilation in general already behaves almost the same between vulkan and d3d12, and vkd3d-proton will show shader stuttering in the same cases where it would also show on native windows, and there is nothing you can do about it.
I see... since I haven't got any more stuttering with D3D9-11 games using Mesa 23.1.X, I thought the same would apply for D3D12 as well. Thanks for the explanation.

Disney Speedstorm has some minor stuttering during the races (I suppose related to shader compilation since they fade away eventually). Is VKD3D working with GPL ?
