RTX Video Super Resolution is a new AI upscaling tool from Nvidia, though this one's not intended to make your games look or run any better. It is still going to be pretty handy for gamers though, as it takes regular 1080p videos from your browser and transforms them into 4K.
The new tool uses AI to improve the quality of video streaming for recent Nvidia graphics card owners. It works by removing blocky compression artefacts and then upscaling video resolution—so cleaning the input then blowing it up to the big screen. From Nvidia's videos of the feature so far, it appears the only option is 1080p -> 4K upscaling.
