This is really a /g/ question but /a/ has more experience with madVR.
I downloaded the new release of madVR today but now all video is black. Audio still plays.
I am using the same settings that I used with the previous version of madVR. I wanted to try some of the new features but now I can't even play any of my chinese cartoons (obviously I could just downgrade madVR but muh autism doesn't like that).
Try different scaling algorithms. I had this when I tried using nnedi3.
