Be aware that to really see what madVR can do that makes it stand out significantly from say EVR you need copius amounts of GPU horsepower. madVR has many scaling options for upscaling, downscaling and chroma. If you have enough GPU and I mean a lot you can select the highest level of image upscaling and chroma upscaling and the color improves noticeably. For Upscaled SD images you will see very high quality scaling without artifacts. The problem is the very high settings will cause drop frames and stuttering if you are not running heavy hardware.
For SD stuff you can use DXVA upscaling and Jin AR 3 Chroma upscaling with something like a GT 650 Ti or better. I am using an AMD HD 7790 ( theoretically a step up from the 650 Ti and I can not find settings that work across the board for all media types. So while one setting is working for SD, that setting won't work for OTA Broadcast HD. The setting for OTA HD Broadcasts may drop frames with HD Ceton Cable Broadcasts on a given day. I have spent a dozen hours screwing around with this and it has become clear that the 7790 doesn't have the cajones do what I need. It does very nice work with WMC though.........
The AMD HD 7790 theoretically should be enough card but from what I can run into, you need more AMD card pound for pound to get the same job done, than you do with Nvidia. I have a problem (audio bug) wtih Ceton Cable HD Playback with Nvidia and that's why I bought the AMD. The 7790 card should have enough poop to run the madVR settings I elect for all my content and sometimes it will and sometimes it won't. I think this may have to do with some aggressive thermal management that keeps the 7790 down to 85 watts TDP.
For now the driver the 7790 is running It is pretty much a first version one off of the driver as the card is very new, the driver is in fact specific to the card. I now wish I would have gone with a 7850 or 7870..Yes they would have used more power but they have signifcantly higher bandwidth and usee the standard driver which is quite mature.
Between the nad/R renderer and LAV Video there are so many different combination of switches that getting the most out of madVR might drive you crazy, especially if you card doesn't have an abundance of processing power. When you start to read in detail about madVR and LAV you see that the majority of the testing and development was done with Nvidia and or Intel, AMD has been an after thought and it shows in the way it runs. I have some older Nvidia cards that are much less powerful that work easily and well with the madVR/Lav combination. They don't the juice to run the high settings but they configure much more easily and once set they just seem to work. If I didn't not have audio problems with the Ceton playing back some cable content in WMC with Nvidia I would get a GT 660 and live with the heat and power consumption.
