AMD Brings FSR 4.1 Upscaling to Radeon RX 6000, Xbox Series X/S, and Ryzen AI Chips

To run on this older hardware, AMD adapted FSR 4.1's neural network model to work with INT8 shader hardware rather than the higher-precision FP8 matrix acceleration found on the Radeon 9000 cards. The version built for handhelds was reduced further, to under half the size of the full model. AMD states that, compared with FSR 3, affected GPUs and APUs should deliver improved image quality under equivalent settings.

Tom's Hardware reported that in its testing of Cyberpunk 2077 in FSR Balanced mode at 4K on a Radeon RX 6900 XT, running FSR 4 reduced performance by roughly 13%. The outlet noted that FSR Frame Generation should also offer better frame pacing in this release.

The technology arrives through AMD's Adrenalin 26.10.1 WHQL drivers. According to TechPowerUp, the drivers also add support for Call of Duty: Modern Warfare 4, STAR WARS: Galactic Racer, and FINAL FANTASY RESONANCE, and fix a stuttering issue affecting Call of Duty: Modern Warfare 4 on RX 6000 series and newer products.

Michael Dell says tight DRAM and HBM supply, driven by AI data center demand, will worsen next year, with relief unlikely before 2029.
