AMD’s Adrenalin 26.10.1 driver, released on October 20, adds FSR Upscaling 4.1 for the Radeon RX 6000 series, the RDNA 2 generation that first shipped in 2020. In its announcement, AMD says its machine-learning upscaling delivers a significant leap in image quality over FSR 3.1, the version RX 6000 owners had until now.
RX 6000 receives the INT8 model that RX 7000 got in July
FSR 4 launched in 2025 exclusively on the Radeon RX 9000 series, and FSR Upscaling 4.1 reached the RX 7000 series in July 2026. For the RX 6000 cards, the company optimized the INT8 model originally built for the RX 7000 generation. Ryzen AI 9 laptops and the Ryzen Z2 handheld chips get a different build: a more efficient version described as purpose-built for that class of hardware. On Ryzen AI Max laptops and mini-PCs such as the Ryzen AI Halo, FSR 4.1 makes its official debut on mobile APUs.
The driver covers cards and laptops today, while handhelds and Xbox are listed separately
The announcement lists a wider set of devices than the driver installs on. The 26.10.1 release notes cover the RX 6000 series, Ryzen AI Max 300 and 400, and Ryzen AI 9 300 and 400, with compatible cards in the RX 6900, 6800, 6700, 6600, 6500 and 6400 families. Z2 handheld processors do not appear in that list. AMD notes that availability and timing vary by device and points handheld owners to their manufacturer for official timelines. Xbox Series X and S support is coming soon, as the Xbox CTO confirms in the announcement video. The ROG Xbox Ally X is among the devices AMD lists as benefiting, but that benefit arrives through ASUS rather than through this download.
In practice, an RX 6000 desktop or a Ryzen AI Max laptop can update today. A Z2 handheld waits for its maker’s driver, and a console waits for Microsoft.
AMD gives no performance cost for the older cards
AMD frames the gain in image quality and in the number of supported devices, with no frame rates or per-card performance cost. On the RX 6000 series, a neural model on hardware that first shipped in 2020 may cost more frame time than FSR 3.1 at the same render resolution, so whether it pays off at the Balanced or Performance presets depends on measurements AMD has not published.
The same driver also fixes stuttering in Call of Duty: Modern Warfare 4 on RX 6000 cards and newer, per the release notes.
