AMD Announces FSR 3.1: Seriously Improved Upscaling Quality

AMD's FidelityFX Super Resolution 3 technology package greatly enhanced FSR technology on Radeon RX 6000 and 7000-series graphics cards last September. But perfection knows no bounds, so this week, the company is introducing its FSR 3.1 technology, which improves upscaling quality, decouples frame generation from AMD's upscaling, and provides FSR for developers. Makes it easy to work together.

Arguably, the main enhancement of AMD's FSR 3.1 is its improved temporal upscaling image quality: compared to FSR 2.2, the image is less reflective at rest and less ghosting when moving. This is a significant improvement, as flickering and ghosting patterns are particularly annoying. Meanwhile, FSR 3.1 has to be implemented by the game developer themselves, and is the first title to support this new technology later this year. Shaft and clinch: rift apart.

Another important development brought by FSR 3.1 is its decoupling from the frame generation feature introduced by FSR 3. This capability relies on a form of AMD's Fluid Motion Frames (AFMF) optical flow interpolation. It uses temporal game data such as motion vectors to add an extra frame between existing ones. This capability can lead to up to two times the performance in compatible games, but was initially tied to FSR 3 upscaling, which is a limitation. Starting with FSR 3.1, it will work with other upscaling methods, although AMD refrains from specifying which methods and on which hardware for now. Also, the company does not disclose when it is expected to be implemented by game developers.

In addition, AMD is bringing support for FSR3 to Vulkan and the Xbox Game Development Kit, enabling game developers on those platforms to use it. It also adds FSR 3.1 to the FidelityFX API, which simplifies debugging and enables forward compatibility with newer versions of FSR.

Following its release in September 2023, AMD FSR 3 was initially supported by two titles, Forspoken and Immortals of Aveum, with ten more games slated to join them. Fast forward six months later, the lineup has expanded to an impressive roster of 40 games either currently supporting or set to soon include FSR 3. By March 2024, FSR will be supported by Avatar: Frontiers of Pandora, Starfield, The Last of Us Part I. Soon, Cyberpunk 2077, Dying Light 2 Stay Human, Frostpunk 2, and Ratchet & Clank: Rift Apart will support FSR. Soon
