Since its initial reveal back in Computex 2025 this June, AMD has been rather quiet on its next-generation upscaling technology in the form of FSR Redstone, but AMD’s Jack Huynh has officially confirmed the launch date: 10 December 2025. This distinctly-named version of FidelityFX Super Resolution suite builds on top of FSR4 – exclusive to Radeon RX 9000 series GPUs – with machine learning being the main driver behind its features.
FSR Redstone Is Almost Ready
Oddly enough, AMD quietly introduced one of Redstone’s features, Ray Regeneration (equivalent to NVIDIA’s Ray Reconstruction), to the just-released Call of Duty: Black Ops 7. It’s only available to the aforementioned Radeon GPUs, and similar to NVIDIA’s implementation, it uses machine learning to perform the denoising process on ray-traced lighting, which is casted in limited capacity to maximize performance at a quality trade-off.
That’s one of the four technologies under Redstone, which also includes ML-based super resolution, ML-based frame generation, and Neural Radiance Caching. NRC is another method of using machine learning to continuously predict where the rays will bounce, saving the computation power beyond the first computed bounces to improve overall performance.
These features require quite a bit of AI compute to work, which is why FSR4, and by extension FSR Redstone, will be limited to RDNA4-based Radeon RX 9000 series GPUs, or any other models that utilize this architecture. There is still more details to be had to see how AMD implements these technologies in specific games, and we’ll have to wait until December to find out.
