render method - DXVA-HD (I messed with that a lot, found that either auto, DXVA, or DXVA-HD didn't make a huge difference in performance, so I stuck with DXVA-HD).
HQ Scaling - 0% for now. I messed with numbers like 50%, even 100%, but again wasn't one that had big impact on performance
DXVA2 enabled (not sure why the pic you showed has VDADecoder, I dont' have that option)
Deinterlace -off. I have to leave this off, with it set to "on" or "auto", I see obvious artifacts like text shimmering & diagonal lines look like crap.
Scaling method - bicubic. I think that is one of the simplest scaling methods available. If I leave it at auto, the picture totally screws up (unless I set xbmc to run fullscreen window instead of true fullscreen). I know Lanczos 3 is apparently the best, but it unfortunately lowers performance.
Rest is all defaults. I spent weeks playing with diff settings... some of those settings above don't have huge impact on performance and you could probably change & still work fine. The biggest ones for me were to leave de-interlace off, and to have the GPU do all the rendering possible.
