With FSR 3.1.4, AMD is laying the inspiration for “Redstone,” which is ready to reach later this yr as a significant upscaling replace for present Radeon graphics playing cards.
At Computex 2025, AMD introduced a brand new replace for upscaling in FSR 4 (“FidelityFX Tremendous Decision”). The mission, dubbed “Redstone,” is meant to enhance implementation in three key areas; the discharge date was set for the second half of 2025.
The corporate has now laid the inspiration for this, as defined within the GPUOpen developer weblog. This step is mirrored within the replace to FSR 3.1.4, which is now obtainable.
AMD Redstone: 4 factors for a hallelujah
The precise replace to FSR 3.1.4 may be summarized fairly rapidly. In comparison with its direct predecessor, solely minor ghosting points have been mounted.
Nevertheless, issues get thrilling within the subsequent sentence of the developer weblog, as a result of “FSR 3.1.4 additionally provides the mandatory digicam parameters to help ML body technology” – i.e., a part of the aforementioned Redstone characteristic set. Since recreation builders ought to be capable to change from FSR 3 to FSR 4 comparatively simply, this is a crucial replace.
Mainly, Redstone needs to trigger a stir with 4 totally different factors:
Neural Radiance Caching: This expertise makes use of a grid of AI-powered neural networks that constantly be taught from recreation knowledge and predict how mild will unfold in a scene.
ML Ray Regeneration: Goals to deal with one of many primary issues with ray tracing: the excessive variety of samples required for clear photographs. As an alternative of counting on standard denoising algorithms, this AI-based answer reconstructs lacking pixel info.
ML Body Technology: Whereas AMD nonetheless relied on vector-based body technology in FSR 3, Redstone is introducing a totally AI-based answer – and that’s precisely what FSR 3.1.4. relies on.
ML Tremendous Decision: The identical applies to the precise upscaler, the place AMD makes use of an ML-enhanced AI mannequin to provide higher photographs, particularly at low beginning resolutions.
Nevertheless, there may be nonetheless a draw back to Redstone, as the brand new options are solely obtainable on the RDNA 4 structure. Because of this solely the Radeon RX 9070 (XT) and RX 9060 (XT) can profit from the improved options. AMD seems to have deserted plans to convey the brand new applied sciences to older generations.
