The next chapter of AMD’s upscaling technology has officially arrived. AMD has launched the full feature set for FSR “Redstone,” following the initial roll-out of Ray Regeneration in Call of Duty: Black Ops 7 in November. Delivered through the AMD Software: Adrenalin Edition 25.12.1 driver update, FSR Redstone represents a major evolution in FidelityFX Super Resolution, bringing machine learning-powered upscaling and frame generation to gamers.
FSR Redstone marks a clear shift in AMD’s approach, combining traditional rendering efficiency with advanced neural networks to improve image quality, ray tracing performance, and frame rates. The result is a more complete and forward-looking solution that targets modern GPUs and next-generation game engines.
One of the headline features is FSR Ray Regeneration. This technology uses a neural network to clean up noisy ray-traced reflections and shadows before upscaling and interpolation are applied. By improving ray tracing data at an earlier stage, AMD can deliver sharper, more stable visuals with fewer artefacts. Ray Regeneration is currently supported in Call of Duty: Black Ops 7, with more titles expected to adopt the feature over time.
FSR Redstone also introduces Radiance Caching, a new technique designed to predict light behaviour in ray-traced scenes. By intelligently estimating how light interacts within an environment, Radiance Caching accelerates ray tracing workloads while preserving visual fidelity. This feature is available now for developers via GPUOpen, with in-game implementations expected to arrive in 2026.
Building on the momentum of FSR 3.1, FSR Redstone further enhances upscaling and frame generation through machine learning. These improvements are designed to deliver higher image quality, smoother motion, and better performance, particularly on AMD Radeon RX 9000 Series GPUs. The focus remains on broad compatibility while pushing visual quality closer to native rendering.
With FSR Redstone, AMD is signalling its intent to compete aggressively in the evolving space of AI-assisted graphics. By unifying ray tracing enhancements, predictive lighting, and machine learning-based upscaling under one framework, FSR Redstone positions itself as a cornerstone of AMD’s graphics strategy for the years ahead.
