I wouldn't use Nvidia DXVA scaling anyways because the image will be softer. It uses Bilinear, as where Pixel Shaders can be set to Lanczos3, which is much better quality.

There is a chart of Kodi scaling settings here: https://forum.kodi.tv/showthread.php?tid...pid1966608

I might have to try more different sources, but on the videos I tried yesterday, Lanczos3 produced a quite visible grain in lots of areas -- but it was definitely sharper. So I gather that the solution is trying the pixel shader filters until I'm happy with one of them, and forget about dxva (and its problems )
