With today"s new WHQL certified Adrenalin 22.3.1 driver, AMD has introduced its new Radeon Super Resolution (RSR) upscaling technology. RSR is based on FeidelityFX Super Resolution (FSR) 1.0 which means it utilizes spatial upscaling instead of temporal that you will find on the upcoming FSR 2.0. Despite being based on FSR 1.0, which is supported by all Radeon GPUs since Polaris (RX 400/500), RSR, for now at least, is only available on Navi or RDNA cards, which means you need to have Radeon RX 5000 or 6000 GPU.
However, RSR has a major advantage over FSR as it can be utilized in any game, without needing developer integration, as long as it supports exclusive fullscreen. All you have to do is to enable a toggle inside the Radeon Software.
AMD says there are big gains to be had with RSR enabled and has provided some of its own figures in five titles.

To measure some of the claims, PCWorld decided to test the feature in Cyberpunk 2077 on a Radeon RX 6700 XT. 2160p (4K) native performance was tested against 1440p upscaled to 4K using RSR. Two images showing the results have been given below (click to enlarge). The image on the right is a zoomed in version of the same scene in order to focus on the minor details.

As you can probably notice on with the image on the right, with a 166% zoom, the palm tree definitely appears more pixelated and in need of some anti-aliasing (AA). Perhaps a future RSR technology based on FSR 2.0 can solve the issue as the new FSR implementation uses its own optimized AA method. But for now, RSR looks impressive especially considering it doesn"t even require a per-game implementation.
