Nvidia announced that starting in February, PCs with RTX 40 series or 30 series GPUs will upscale 1080p videos to 4K in the Google Chrome and Microsoft Edge browsers. It's unclear why it won't work on RTX 20 series GPUs, which have DLSS functionality similar to the 30 series.

As part of its "Nvidia Studio" announcements at CES 2023, Nvidia unveiled a short video demonstrating RTX Video Super Resolution. The clip compares 1080p Apex Legends gameplay with the footage upscaled to 4K. A zoomed-in shot shows that the upscale effect smoothens blocky artifacts on near and far objects.

The company's well-known DLSS feature upscales games from and to a broader range of resolutions through its quality, performance, and ultra-performance modes. Focusing first on upscaling from 1080p makes sense, as it's likely the most common web video resolution. Hopefully, Nvidia will eventually try to add upscaling from 720p. The results might not look as good, but there's enough 720p content on the web to warrant testing.

Features that can appeal to non-gamers as well as to users who are not gamers should be adopted more and more to showcase the quality of graphics cards.(y)

NVIDIA is releasing a new GeForce Game Ready driver (version 531.14) today, and its main feature is the support for RTX Video Super Resolution.

Enabling RTX Video Super Resolution is extremely easy. You'll just have to open up the NVIDIA Control Panel app and head to the Adjust Video Image Settings tab under Video. There, near previously available features like edge enhancement, noise reduction, and deinterlacing, you'll find the RTX video enhancement box. After ticking the box, you will also have to select the Quality setting, which ranges from 1 to 4. According to NVIDIA, level 4 provides the best quality by augmenting the complexity of the underlying algorithm, but it also uses more GPU power than lower levels.

In our testing, we checked out the same Twitch video FullHD recording (Avalanche Software's Tech Test feat. Guest Host!) on both Chrome and Mozilla Firefox, which doesn't support RTX Video Super Resolution. As you can see, alt-tabbing between the two windows shows an immediately noticeable sharper picture when using Chrome. Everything, from the faces of the hosts to the finer details in the background, including the sword's pommel, is much clearer with the enhancement provided by RTX VSR at the maximum level of quality.

Nvidia's latest GPU driver introduces its new AI-based upscaling technique for making lower-resolution videos streamed offline look better on a high-resolution display. Now available via the GeForce driver 531.18 released on Tuesday, Nvidia's RTX Video Super Resolution (VSR) successfully cleaned up some of the edges and blockiness of a 480p and 1080p video I watched on Chrome using a 3080 Ti laptop GPU-powered system, but there are caveats.

By Nvidia's measures, 90 percent of video streamed off the Internet, be it from Netflix, YouTube, Hulu, Twitch, or elsewhere, is 1080p resolution or lower. For many users, especially those with Nvidia GPU-equipped systems, when moving to 1440p and 4K screens, browsers upscale this content, which can result in image artifacts like soft edges.

Nvidia VSR, which (somehow) shouldn't be confused with AMD VSR (Virtual Super Resolution, targeting lower-resolution displays), uses the AI and RTX Tensor cores in Nvidia's 30- and 40-series desktop and mobile GPUs to boost sharpness and eliminate "blocky compression artifacts" when upscaling content to 4K resolution, per a blog post Tuesday by Brian Choi, Nvidia's Shield TV product manager.

MPC VideoRenderer with code to enable NVIDIA RTX VSR & Intel Xe VPE.

Tested with the Feb 2023 MPC-BE 1.6.6 release, also known to work with clsid2's updated MPC-HC fork, and most likely other DirectShow-based players too (ie: anything that worked with madVR)

480p madVR NGU Sharp comparison: NGU Sharp vs NV VSR - Imgsli
480p disabled/enabled comparison: superres mpc-be - Imgsli




Seeing this implemented officially in media players (VLC, Potplayer, MPC) would be cool.

It uses way too much power for the benefits you get. Hopefully they can optimize it.
