AMD has launched FSR Redstone, accessible through the AMD Adrenalin 25.12.1 driver, featuring FSR Frame Generation, Ray Regeneration, and Radiance Caching, along with enhanced FSR Upscaling technology, compatible exclusively with RDNA 4 hardware (Radeon RX 9060 XT and RX 9070 XT/RX 9070 GPUs). Ray Regeneration will debut in Call of Duty: Black Ops 7, with plans for future titles. The update aims to improve image quality and performance, closing the gap with Nvidia's DLSS 4 technology. However, it lacks backward compatibility with older GPUs, limiting its use to RDNA 4 hardware. FSR Radiance Caching is expected to enhance ray tracing performance in 2026, and the FSR Redstone SDK will facilitate easier integration into games.
