I've been using madVR for some years now and I remember looking at my room-mate's monitor when he was watching HD films and thinking they looked horrible - like DNR was applied to them or something (I told him as much but he didn't care) I put it down to his monitor doing it, because he was using MPC-HC, just like me but then one day I installed MPC-HC on the new computer and suddenly videos looked exactly like on my friend's computer, so I started digging and found out, that I accidentally left EVR as the renderer and when I switched to madVR, the difference was night and day - I actually took these screenshots back then to show my friend to convince him to let me switch his settings to madVR too :-)
