AMD launched its FSR "Redstone" update in December 2025 as part of the AMD Adrenalin 25.12.1 driver package, bringing to a close months of speculation after the upgraded upscaling tech was first revealed at Computex 2025.
As expected, AMD's ML-powered FSR Redstone update launched with availability only for its latest Radeon RX 9000 graphics cards using the RDNA 4 architecture. PC gamers using AMD's older RDNA 3 GPUs were largely left out in the cold, watching as adopters of the newer hardware got to test out new FSR Upscaling, Frame Generation, Ray Regeneration, and Radiance Caching techniques.
