THE CRUNCH
AMD has announced FSR 4.1, its machine learning upscaling technology, for Radeon RX 6000 series graphics cards, a wide range of Ryzen APUs and handheld chips, and Xbox Series X and Series S consoles. The RX 6000 support, covering RDNA 2 cards from the RX 6950 XT down to the RX 6400, is available today with the Adrenalin Edition 26.10.1 drivers, as is support for Ryzen AI Max 300 and 400 series and Ryzen AI 9 300 and 400 series devices. Xbox console owners will wait a little longer: Microsoft's Jason Ronald says it will be available to developers "very soon", with no exact date given.
Getting there required real engineering. AMD says it reworked FSR 4.1's neural network model to run on the INT8 shader hardware in older cards, rather than the higher-precision FP8 acceleration found in Radeon RX 9000 GPUs, and slimmed the handheld version to less than half the size of the full one. Tom's Hardware's quick test with an RX 6900 XT in Cyberpunk 2077, FSR Balanced mode at 4K, found FSR 4 costs about 13% performance in exchange for sharper, more stable visuals.
The rollout is ahead of schedule. RX 6000 support had been promised for early 2027, and AMD had said earlier this month that FSR 4 would reach APUs and handhelds by the end of the year. AMD says the update also brings better frame pacing to FSR Frame Generation, with Vulkan support and wider FSR Ray Regeneration coverage to follow; Ray Regeneration is live now in Warhammer 40,000: Darktide.
The Xbox news puts Microsoft level with Sony, which introduced its own QSSR upscaling for the standard PS5 just weeks earlier. Handheld and console updates will arrive via manufacturers, since those devices depend on OEM-specific drivers, and Xbox CTO Scott Van Vliet points to more ahead through Project Helix and FSR Diamond.
