FSR “Redstone” is here, and it’s the future of gaming
AMD FSR Radiance Caching
Radiance Caching is available to developers today
AMD’s FSR Radiance Caching is a real-time neural-network-based radiance-caching technology. It accelerates ray tracing by using a neural network to infer radiance results sooner. This allows for accurate ray tracing results without “brute force” computation. This allows for high levels of image quality without insane computational cost.
With FSR Radiance Caching, AMD wants to make intensive ray-traced lighting effects much less demanding on gaming hardware. This tech is available starting today though GPUOpen, allowing developers to integrate it into their games. The first FSR Radiance Caching-enabled games will become available in 2026.
Below, we can see FSR Radiance Caching in action in Warhammer 40,000: Darktide. Sadly, we do not have framerate data for this scene running with and without FSR Radiance Caching. However, it does showcase FSR RC’s ability to light complex scenes.
Available now (To Developers)
AMD’s FSR Radiance Caching technology is now available to developers via GPUOpen. We expect to see direct game integrations for this technology in 2026.
