AMD implements v1.0 of FSR into RSR. FSR is used to render games at a lower resolution than the native resolution of the screen and then scale them up to the native resolution of the screen. However v2.0 is under development and provides "next-gen image upscaling". 

AMD FidelityFX Super Resolution 2.0 is scheduled to be revealed in the upcoming months and is believed to have temporal upscaling and enhanced anti-aliasing. The second iteration of AMD FidelityFX Super Resolution (test) is expected to work on all graphics cards from all manufacturers and provide improved image quality. AMD is trying to integrate FSR 2.0 with a number of modern gaming engines and games that are either already available or in development.

AMD will offer a more extensive presentation, including an inside look at how FSR 2.0 works, at its GDC 2022 presentation on March 23, 2022. The business intends to offer FSR 2.0 to players in the second quarter of 2022. (between May/ June).
