Nvidia RTX Super Resolution seems to only work very rarely or not at all compared to the Chrome version. In some instances it will upscale the Full-Screen Video. It will not interact with windowed videos at all. But it will never upscale a windowed version that exceeds the playback resolution. '''Steps to reproduce for windowed videos:''' # Open any youtube video # Set the resolution to 480p or lower (as I am using a QHD 2560 x 1440p monitor) # Playback the video and monitor Nvidia Control Panel to see if Super Resolution has activated. '''Observation for windowed videos:''' Feature works in Chrome. Feature does not work in Firefox '''Full-Screen and Super Resolution:''' I have no idea what is going on here, on very rare occasions it does work, for the most part it does not work at all. If I had to give a rough idea of when it works, I would say that it is more likely to work when Firefox has been freshly launched. I could neither see an active change in the Control Panel, or notice anything in the video quality. Both a quality change and feedback in the Control Panel occur when using the feature in Chrome. I have tested on identical links, with identical quality settings. '''I tried:''' * setting the Super Resolution Quality manually, instead of manually * an incognito tab
