While the original FSR 3.0 feature-set largely carries forward the super resolution upscaler from FSR 2.2, adding frame generation on top; the new FSR 3.1 adds several image quality improvements to the upscaler itself, improving image quality at every performance preset. Specifically, it improves the temporal stability of the output at rest and in movement, to reduce flickering and shimmering, or "fizziness" around objects in motion. The new upscaler also reduces ghosting, and better preserves detail.
Next up, is a rather important change in the way the frame generation technology works. AMD has decoupled FSR 3.1 frame generation from the upscaling tech, which allows frame generation to work with other upscaling solutions, such as DLSS or XeSS. The possibilities of such a decoupling are endless—have an RTX 30-series "Ampere" GPU that lacks DLSS 3 frame generation support? No worries, use DLSS 2 for the upscaling, and FSR 3.1 for the frame generation. AMD is also clumping its FidelityFX family of technologies into a new FidelityFX API that makes it easier for developers to debug, and paves the way for forward-compatibility with future versions of FSR. Lastly, FSR 3.1 supports Vulkan API, and the Microsoft Xbox GDK. AMD plans to release FSR 3.1 to developers through its GPUOpen platform in Q2-2024, and its first implementations on games are expected later this year. In the meantime, AMD implemented FSR 3.1 on "Ratchet & Clank: Rift Apart," to showcase the new upscaler.
It's a very nice upgrade.
