FSR “Redstone”: AMD Unveils Complete Feature Set
With Redstone, AMD aims for an increasingly competitive rendering platform
AMD takes a decisive step in its technological roadmap by officially presenting the complete feature set of FSR “Redstone”, an evolution of the FidelityFX Super Resolution ecosystem. Following the debut of Ray Regeneration last November in Call of Duty: Black Ops 7, the company now expands the package by introducing machine learning-based upscaling and advanced frame generation.
All new features are already available via the new AMD Software driver: Adrenalin Edition 25.12.1, downloadable today.
Extended Compatibility
The core of Redstone is articulated into 3 key technologies. The first is FSR Ray Regeneration, which leverages a neural network to improve ray-traced reflections and shadows by reducing noise before the upscaling and interpolation phases. It is currently supported in Call of Duty: Black Ops 7, but AMD confirms that other titles will adopt it in the coming months.
The second is FSR Radiance Caching, designed to predict light behavior and lighten the ray tracing load while maintaining high visual fidelity. The function is already available to developers on GPUOpen and will debut in games in 2026.
Finally, the new module arrives: FSR Upscaling and Frame Generation, a direct evolution of FSR 3.1, now enhanced by machine learning to ensure superior image quality, particularly on Radeon RX 9000 series GPUs.
