Summary0000343: frame drops in 60fps videos with image doubling NNEDI3
DescriptionPlaying any 60fps 720p video in fullscreen mode with image doubling set to NNDEI3 64neurons(tried 32, drop lessen, but still here) causes dropped frames, as if my video card isn't good enough to play it. Render time is ~26ms though, so there shouldn't be any drops theoretically.

60 fps needs rendertimes below 16.67 ms.

huhn is right, of course. Your render times need to be lower than the "movie frame interval". So this is not a bug in madVR.

It might make sense in your situation to use profiles to use different NNEDI3 settings for 720p60 files, compared to 720p24 files. 720p60 files need 2.5x more GPU power than 720p24 files.
