performance should be fine, especially with the second settings. not really sure what the problem would be.
update intel gpu drivers maybe? or maybe even just a restart of the pc will do the trick.
also, if the video is telecined, force film mode in madvr>processing>deinterlacing
and smooth motion on should benefit you at 60hz.
press ctrl+j while the video is playing, and make sure all the queue values are almost full, and the times listed in your average stats are low.
Using settings: Bicubic 25+AR, DVXA2, DVXA2 with smooth motion on and film mode on
I cannot get smooth playback of SD sources (DVD rips in VIDEO_TS). I tried WMC and that has smooth playback, but the picture comes no where close to madvr.
In average stats. the rendering is 27.50ms the rest are under 1 ms.
