NVIDIA introduced DLSS supersampling anti-aliasing technology, and AMD built its own FSR. NVIDIA has newly upgraded NIS image scaling technology, open source and support for all games, and AMD is also fighting back.
AmD is developing a broaderly applicable anti-aliasing technology, known as Radeon Super Resolution, or RSR for short.
Both DLSS and FSR technologies need to play a role in the graphics rendering process, so they must be supported by game developers, or integrated into the engine, or integrated into the game.
RSR is based on the FSR 1.0 algorithm, but is directly integrated into the Radeon driver software, so there is no longer a need for separate optimization support for the game, and theoretically any game can be used.
The only exception is the full-screen mode that doesn't fit into bezel-less windows, but today it's basically not a thing, and it doesn't rule out that support will be provided in the future.
AMD RSR technology will be officially released next month, supporting RDNA RX 5000 series, RDNA2 RX 6000 series graphics cards, and may support older models in the future.
