Nope not yet but when it does do I change copy back to d3d11 what does that do? Thanks

D3D 11 doesn’t use system memory to copy-back the decoded data. It is the same thing in the end, so either will work.

There might be something in trade quality for performance to help with 4K downscaling. This uses a lot of resources. Chroma upscaling is applied and then the image is downscaled. You might be able to avoid the chroma upscaling with trade quality for performance. I can’t remember. You could be stuck with DXVA2, which is fine.
