[QUOTE="el Filou, post: 1235578, member: 78516"] Hi. When you say DX11 (D3D11), do you mean Copy-Back D3D11 or Native D3D11? Native D3D11 is obviously the best option, but deinterlacing doesn't work yet so if you want to watch TV content you're forced to use Copy-Back D3D11 for now, and I've just done the same test as you and I don't get the same results: :confused: I'm also using a 1050 Ti, driver 388.59 on Windows 1703, display is 1920x1080, latest madVR with D3D11 presentation, in Windowed mode.
