Will do some tests with V320 and MadVR V0.92.2 early afternoon an then report back.@Helios61 are you able to confirm ?
I'm not sure that is a good idea, I recall that somewhere in the Doom9 forums Mahdi had written that DXVA2 Native and Madvr was a nono not sure if that is still the case but!!!!!. Also I did try Native to avoid the old "long stop" problem with Copy Back, (somewhere in this thread ages ago) can't recall whether it was with my AMD RX 460 or the Nvidia GTX 1050Ti though, but the PQ with HEVC TV was rubbish. DXVA2 Copy Back works for me except for the green screen problem which is also a problem with Native (root cause seems to be Nvidias low resiliance to minor interference, not a problem with AMD) but was fixed with Cuvid which was why I was initially so pleased with it. I need to play some more with Madvr settings and the new version and also take a look at the D3D11 option.For nVIDIA Cards simply use DXVA2 native.. it works perfect on all resolutions and all codecs on my system.
