AMD FSR Redstone is rolling out today, December 10, and it is locked to Radeon RX 9000 GPUs at launch. The update adds four AI features—Ray Regeneration, Neural Radiance Cache, AI Super Resolution, and AI Frame Generation—aimed straight at Nvidia’s DLSS 4 stack. In simple terms, AMD FSR Redstone tries to clean up ray-traced effects, predict lighting, upscale your image, and then add extra frames on top for smoother gameplay. Call of Duty: Black Ops 7 is the first game using Ray Regeneration on PC with RX 9000 cards.
| Feature | What It Does (Short) | AMD FSR Redstone Scope |
|---|---|---|
| Ray Regeneration | Cleans up noisy ray-traced reflections and lighting. | RX 9000 only at launch. |
| Neural Radiance Cache | Predicts and caches indirect lighting to speed up GI. | RX 9000 RDNA 4 GPUs. |
| AI Super Resolution | Upscales lower-res frames with an ML model. | Part of FSR Redstone suite. |
| AI Frame Generation | Inserts AI-generated frames to boost FPS. | RX 9000 exclusive initially. |
What AMD FSR Redstone Actually Does
AMD FSR Redstone is a four-part AI toolkit for RDNA 4 and Radeon RX 9000, not just a single toggle in your settings. Ray Regeneration and Neural Radiance Cache handle the heavy lifting for ray tracing and lighting before the image is upscaled or frame-generated.
Ray Regeneration uses a neural model to clean up noisy ray-traced reflections and lighting instead of relying only on traditional denoisers. Neural Radiance Cache predicts indirect lighting and caches it so scenes with global illumination can run faster without brutal performance hits. AI Super Resolution then upscales a lower-resolution frame to a sharper final image, while AI Frame Generation adds in-between frames to push FPS higher when the feature is enabled.
RX 9000 Exclusive at Launch
AMD FSR Redstone is currently described as focused on Radeon RX 9000 and RDNA 4 GPUs only, with no confirmed support for older Radeon hardware. Reports and official teasers repeat that the new FSR Redstone features are “for Radeon RX 9000 Series,” and there is no public compatibility list that includes RX 7000 or RX 6000.
Community posts and some technical discussions bring up the idea that parts of Redstone could be made to run on other GPUs, but AMD has not promised that in any official channel. For now, anyone who wants AMD FSR Redstone with Ray Regeneration, Neural Radiance Cache, AI Super Resolution, and AI Frame Generation should treat RX 9000 as a requirement.
Games and How It Stacks Up to DLSS 4
Right now, Call of Duty: Black Ops 7 is the showcase title for AMD FSR Redstone Ray Regeneration on PC with RX 9000. AMD’s teasers and coverage from hardware sites point to more games picking up Redstone features after the December 10 launch, but there is no full public game list yet.
Feature-wise, AMD FSR Redstone goes after the same problems as DLSS 4: AI upscaling, AI frame generation, and smarter ray-traced lighting. DLSS still has a head start on game support, but AMD FSR Redstone gives RX 9000 owners a comparable AI toolkit that lives entirely on AMD hardware.
