The demo clip Nvidia provides (opens in new tab) shows a much clearer improvement with VSR enabled, though it's a more detailed scene where the increase in contrast I noticed on previous streams does show up more clearly. Though even at 1080p I don't notice a huge step up versus native 1080p content, either. Nvidia's game upscaling technology, DLSS (which is "completely different," by the way), runs at much higher native resolutions to imitate a 4K picture than what I'm trying to ask VSR to do here. There's only so much you can expect RTX VSR to do. I didn't feel like I was necessarily watching a 4K video, or even a 1080p video, with VSR enabled on a lower-resolution stream, but more a 480p stream with a higher bitrate. It doesn't look to be adding data so much as making what's there a bit more easy on the eyes. It appears to me more like a blemish-reducing filter for low quality video, taking the worst patches of visual artefacting and smoothing them out for clarity. What VSR doesn't appear to do is necessarily upscale the image how you might expect it to. The game's UI was also marginally easier to read, though this effect is more noticeable in still screenshots than the actual live feed. Contrasting objects appear a little clearer with VSR enabled, and you can just about make out more during patches of fast motion, such as running through a forest from half-naked cannibals. Other gameplay was also sharper and easier on the eyes. Accounting for only a tiny number of pixels in a 480p image, the webcam on the non-VSR stream was tough to discern, whereas it was clearer in the VSR-enhanced stream. One of the most noticeable improvements was the webcam portion of the stream. Whereas it would drop on the VSR stream but the artefacts were no longer as noticeable, or in some cases entirely gone. Especially when Stodeh moved the camera around swiftly, the image quality drastically dropped on the non-VSR stream. What I found was that the stream with VSR enabled suffered less from the very obvious compression artefacts present on the non-VSR stream. I've opted for 4 for all my testing to see what this algorithm can really do. There are four stages of VSR upscaling, 1 being the lightest touch and 4 being the most intensive. Here's a pretty basic diagram provided by Nvidia on how RTX VSR works.
