copyback can't cost you 9 ms that would mean the copy is so slow you can't use it for 120 FPS content because the copyback is using 100 % of the GPU. according to your sig you are running a 1080 ti so just no :-) how do i even play anything on my 1060 if a 1080 ti nearly dies to copyback.

I don’t understand a word of what you are saying. 22ms isn’t “dying”, it’s about half of what it has to do at 23p, and that’s with a lot of processing (HDR tonemapping with everything enabled). Copyback costs 6ms in D3D11 and 9ms in DXVA2, at least in that mode, and it does push GPU and CPU to 100%, even at native res, but again that’s with very hungry pixel shader processsing. I’m only reporting what I’m seeing. And yes, I have a 1080ti, otherwise I wouldn’t put it in my sig.
