FSR Redstone is AMD's most advanced leap in upscaling and rendering, debuting officially on December 10. It's exclusive to Radeon RX 9000 series (RDNA 4) and finally brings full machine learning into frame generation, super resolution, ray regeneration, and radiance caching. Redstone aims to close the gap with Nvidia’s DLSS, focusing on sharper visuals and smoother performance. New ML-powered ray regeneration replaces traditional denoisers, improving clarity.

Digital Foundry tests in Black Ops 7 show almost no performance cost, with only a 1 FPS drop versus the standard method, but a noticeably cleaner image, especially in reflections. Users can expect significant gains in ray-traced scenarios reports show FPS increases from the upper 30s to nearly 70 in high-RT scenes when using FSR 4 quality mode.

However, native performance uplift without ray tracing is mild. AMD’s new neural radiance caching also boosts lighting realism without heavy hardware load. For now, features remain limited to RDNA 4, but future support for other GPUs isn't ruled out.
