At GDC 2022, AMD is revealing more details of their recently announced FSR 2.0 'FidelityFX Super Resolution' technology. Not only does the new tech improves upon FSR 1.0, offering better image quality but has wider support across various graphics cards from NVIDIA and AMD themselves & also allows developers to integrate it within games faster than ever.

Coming in Q2 2022, FSR 2.0 will offer various quality modes to gamers to get the balanced image quality and performance. There will be three primary modes, Quality, Balanced, and Performance like before but enhanced to offer better image quality and performance through the temporal upscaling techniques which bypass the requirement of ML (Machine Learning). AMD does point out that Machine Learning implementations do have their advantages but are not necessarily a pre-requisite to achieving better image upscaling.
