AMD has announced the release of FSR 4.1, significantly broadening the compatibility of its upscaling technology. Previously, FSR 4 was exclusive to Radeon RX 9000 series graphics cards and later extended to RX 7000 series. The FSR 4.1 update now includes support for Radeon RX 6000 series cards, Xbox Series X and Series S consoles, and Ryzen Z-series handhelds, as well as machines equipped with Ryzen AI Max and AI 9 chips.
To enable this expanded support, AMD modified FSR 4.1's neural network model. The updated model now supports INT8 shader hardware, which differs from the higher-precision FP8 matrix acceleration hardware found in Radeon 9000 cards. For handheld devices, a slimmed-down version of FSR 4.1, less than half the size of the full version, was developed.
AMD states that FSR 4.1 delivers better image quality compared to FSR 3 on the newly supported GPUs and APUs. Testing with a Radeon RX 6900 XT running Cyberpunk 2077 in FSR Balanced mode at 4K showed that FSR 4 incurred approximately a 13% performance cost while providing sharper and more stable visuals. The update also brings better frame pacing for FSR Frame Generation.
The integration of FSR 4.1 is expected to particularly benefit less powerful devices such as the Xbox Series S and the original Ally handhelds. Xbox CTO Scott Van Vilet noted that this technology provides developers with another tool for achieving strong performance and visual quality for players. While FSR 4.1 is expected on the Xbox Ally X before the end of the year, a specific timeline for other consoles is listed as "coming soon."
