Overview
- Redstone bundles FSR Upscaling (formerly FSR 4), machine‑learning Frame Generation, Ray Regeneration, and Radiance Caching; Ray Regeneration is already live in Call of Duty: Black Ops 7 after co‑development with Xbox, while Radiance Caching is SDK‑only with game use expected in 2026.
- AMD says more than 200 games will support Redstone upscaling by year‑end, with roughly 30–40 titles enabling the new ML frame generation at launch.
- Access is restricted to Radeon RX 9000‑series (RDNA 4) GPUs; users enable features in the AMD Software app and often in game menus, and the driver can substitute Redstone Upscaling/Frame‑Gen for titles that already support FSR 3.1 or 4.
- AMD’s own benchmarks claim about 2.2x to 4.7x higher 4K performance when all Redstone features are active in Performance mode, figures that include generated frames and depend heavily on the game and base frame rate.
- Reviews note cleaner images and fewer artifacts versus FSR 3.1, yet Nvidia still holds advantages in backward compatibility and multi‑frame generation support.
