AMD updates FSR SDK with FSR 4.1.1 support for RDNA 3 and improved FSR Ray Regeneration 1.2.0

AMD has released the FSR SDK v2.3.0 for game developers, which allows them to integrate AMD's FSR technologies into their projects natively. This is a notable update because it includes the DLL for the latest version of FSR Upscaling 4.1.1, which adds support for Radeon RX 7000 Series (RDNA 3) discrete GPUs. AMD has already released FSR Upscaling 4.1.1 as part of the latest Adrenalin drivers for Radeon GPUs, allowing RDNA 3 gamers to use the FSR 4 driver override feature, so this is more for future game releases and updates.

Perhaps the biggest addition to FSR SDK v2.3.0 is the arrival of AMD FSR Ray Regeneration 1.2.0. FSR Ray Regeneration is the company's answer to DLSS Ray Reconstruction, as it leverages AI and machine learning to denoise ray-traced lighting effects. The technology is still relatively fresh on the scene and only available in a handful of titles like Call of Duty and Crimson Desert, with the overall effect being an improvement compared to non-AI denoisers, but still a step or two behind DLSS 4.5 Ray Reconstruction when it comes to image quality and detail that's restored.

With FSR Ray Regeneration 1.2.0, AMD notes that this update features "quality improvements," which is great to see, alongside expanding the technology to cover ambient and specular occlusion denoising. These new optional add-ons should bring noticeable improvements to FSR Ray Regeneration's image quality, so it will be interesting to see how they look in-game.

FSR SDK v2.3.0 also introduces FSR Frame Generation 4.0.1, which fixes a couple of issues related to pre-processing motion vectors. It's unclear what effect this will have on the final image and overall performance, but again, it's great to see AMD updating its FSR Redstone technologies as it adds support to more Radeon hardware. FSR SDK v2.3.0 is now available on GitHub.
