AMD releases FSR SDK 2.2 with new AI denoiser Ray Regeneration
AMD’s FSR SDK now includes its new Redstone AI technologies, including render denoiser Ray Regeneration. Images captured on an AMD Radeon RX 9070 XT GPU at 4K resolution.
AMD has released FSR SDK 2.2, the latest version of its SDK for games and CG tools developers looking to integrate its AI rendering technologies into their software.
The update adds AMD’s Redstone neural rendering technologies to the SDK alongside the existing render upscaler, including new AI-based denoiser FSR Ray Regeneration.
A new name for both the SDK and its render upscaling system
The release is a change of branding for the SDK, which provides a set of AI-based render processing technologies for games and real-time apps, and which was previously known as FidelityFX SDK.
AMD has now officially changed that to FSR SDK, to match its best-known component, the render upscaling system, itself now rebranded to FSR Upscaling.
Introduced in 2021, FSR Upscaling is a GPU-based image upscaling system, equivalent to NVIDIA’s Deep Learning Super Sampling (DLSS) and Intel’s Xe Super Sampling (XeSS).
As well as games, it is supported by some CG software, including real-time visualization apps Lumion, where it is used in the editor and render preview, and D5 Render.
Now includes AMD’s Redstone neural rendering technologies
Although FSR SDK 2.2 features a new version of FSR Upscaling, version 4.1 is primarily a performance update, particularly to the dynamic resolution scaling (DRS) mode.
A bigger change is that the SDK now includes AMD’s new Redstone neural rendering technologies.
There are three of them: AI frame-interpolation system FSR Frame Generation, FSR Radiance Caching for real-time GI, and AI denoiser FSR Ray Regeneration.
FSR Ray Regeneration itself has also been updated, with version 1.1 featuring new debug view modes, plus iterative improvements to output quality and memory usage.
At the top of the story, you can see a side-by-side comparison with the standard denoiser in the first game to support Ray Regeneration, Pearl Abyss’s open-world adventure Crimson Desert.
Licensing and system requirements
The FidelityFX SDK 2.2 package is compatible with Windows 10+. It requires DirectX 12. The source code is available under an open-source MIT license.
FSR Upscaling 4.1 and FSR Ray Regeneration 1.1 require Windows 11 and a Radeon RX 9000 Series GPU or better.
