Pfff, amazing MadVR instead of (the good one) EVR.
Watched 240p movies given by my family on Full HDTV.
What can I say :
For 240p, less macroblocks, better smoothed.
For all : More transparency, more mirroring (example, reflects pictures on cars, on flasks of water).
When available, it is worth to take time to configure MadVR, at the end, rendering is amazing and better than EVR.
