AMD has officially expanded its FSR 4.1 machine learning upscaling to Radeon RX 7000 Series graphics cards with the AMD Software: Adrenalin Edition 26.6.2 driver, released June 22. Previously limited to the newer RDNA 4 architecture, FSR 4.1 now covers more than 300 supported games on RDNA 3 hardware.

The Engineering Work Behind the Port

Getting FSR 4.1 to run on RDNA 3 required more than a software toggle. The RDNA 4 implementation uses FP8 floating-point data types to run the upscaling model, but RDNA 3 hardware operates in INT8 (8-bit integer). AMD had to convert the model to run on integer math, which took time and testing. The company says the result is visual fidelity on par with the RDNA 4 version. RX 7000 users are not getting a reduced-quality build, just a different path to the same output.

Game Support and Day-One Titles

The 26.6.2 driver launches with FSR 4.1 support across more than 300 titles already in the library. Two notable day-one additions ship with this driver: Assassin's Creed Black Flag Resynced and DOOM: The Dark Ages | Revelations. Both are among the bigger PC releases this season, making 26.6.2 a priority update for anyone picking up either title at launch.

Who Is Not Covered Yet

RDNA 3 APU owners (those using integrated or mobile graphics on Ryzen processors rather than discrete RX 7000 cards) are not included in this update. AMD says ML models for that segment are still in development and will ship separately. RDNA 2 (RX 6000 Series) owners are further out, with the company targeting early 2027 for that extension.

Why It Matters

FSR 4.1 was the headline upscaling feature of RDNA 4 when the RX 9000 Series launched earlier this year. Bringing it to RDNA 3 matters because the RX 7000 Series represents the bulk of AMD's active discrete GPU user base. Keeping those users on the latest ML upscaling model strengthens AMD's competitive position against NVIDIA's DLSS, where game developers are more likely to support the platform with the larger installed base.

The Adrenalin Edition 26.6.2 driver is available now on AMD's support page. Any discrete Radeon RX 7000 Series card, desktop or laptop, can enable FSR 4.1 immediately after updating.
