I always tought that DivX decoder was the most optimized :confused:

Did you try with the "Force Overlay" checkbox checked in the 3ivx Decoder config?

Might be faster that way

That's right. For me VMR9 is a lot slower than overlay mixer.

Stux i tried all possible combinations but force overlay should force the Video Renderer shouldn't it ? in XviD when YV12 is forced it does but not with 3ivX it stays with the VMR9 renderless renderer that was set in MPC hmm about Overlay Mixer thats not the case here Overlay Mixer is slightly behind (1fps) VMR9 (windowed mode).
But for the Upsampleing Problem i dont advise to use it it's better to use VMR9 Renderless instead, because their everything is as it should be (no color bleeding) and subtitles (MKV) also work :). Those configs only Mirror Nvidia and their drivers not any other Manufacturer.

Could you post the same stats with the same clip, but then without Qpel?
Could be interesting...

Also, what is the fps supposed to be...can't find you saying that.

ahh yes Crusty sorry the Sequence is 25 fps will add it and also a non Qpel test later :)
ok corrected some mistakes and added the Qpel test
