In layman's terms, AMD's FidelityFX Super Resolution (FSR) is an upscaling technology which allows developers to boost the frame rates in their games with only a minor loss in visual fidelity. On top of this, FSR can also provide a sharper image than native resolution in certain cases, again, without sacrificing frame rate.
Certainly, it's one of the most popular upscaling tools along with Nvidia DLSS that the devs can use at the moment.
Recently, AMD revealed FSR 2.0, an updated version of the tech, which brings even better picture quality and performance than the original version. So far, FSR 2.0 was only available to the PC game developers but from now on, FSR 2.0 is also on the Xbox Series X|S developer toolset, which means that Xbox game developers can use FSR on these consoles, the same as on the PC.
Xbox confirmed that the tech works on Xbox One, Xbox Series X|S, and Windows and does not require new hardware.
