FSR 4.1 support for RX 7000 GPUs arrives ahead of schedule with new Adrenalin driver update

AMD has officially pushed FSR 4.1 support out the door ahead of schedule to previous-generation RX 7000 series GPU owners through a new driver update. Adrenalin version 26.6.2 has been released with FSR 4.1 support for RDNA 3 GPUs, along with game support for Assassin's Creed Black Flag Resynced, Doom: The Dark Ages | Revelations, and two bug fixes.

Adrenalin 26.6.2 marks the halfway point in AMD's endeavor to get FSR 4.1 working on older RX 7000 and RX 6000 series GPUs (RDNA 2 support is coming in 2027). Last month, AMD made the announcement to officially support FSR 4.1 on the aforementioned hardware, but confirmed a deadline of July for RX 7000 support, making AMD's latest Adrenalin driver arrival at least eight days early. AMD gamers won't have to worry about quality compromises compared to FSR 4.1 on RDNA 3 GPUs; AMD confirmed that FSR 4.1 on RDNA 3 will feature the same image quality as on RDNA 4 GPUs. The only caveat with AMD's current FSR 4.1 adaptation for RDNA 3 is that only the upscaling portion was ported over, leaving FSR 4.1 frame generation as an RDNA 4 exclusive feature.

Pressure to push FSR 4 to older hardware began almost a year ago when AMD accidentally leaked its own FSR4 source code featuring two versions of the upscaler: the out-of-the-box version with FP8 support and a second build using INT8 instructions. The second version with FP8 support was what grabbed everyone's attention, as it enabled FSR 4 functionality on non-RDNA 4 hardware. Afterward, modders were able to grab the INT8 version (before AMD took down the source code), and implement it in apps such as Optiscaler, enabling users to upgrade supported games from FSR 3 to FSR 4 with the INT8 build.

You can grab Adrenalin 26.6.2 today either through the Adrenalin control panel or through AMD's website and enjoy the benefits of FSR 4.1 if you own an RX 7000 series GPU (and RDNA 3.5 iGPUs). As previously mentioned, RX 6000 series support will be arriving next year, likely due to the fact that these GPUs lack AI-accelerators entirely. If this is true, AMD likely needs the extra time to further optimize the ML-upscaler to run on RDNA 2's shader cores. (This also means AMD can technically bring this version of FSR 4 to non-AMD GPUs, but only time will tell if that will happen.)

Fixed Issues

• Intermittent application crash or driver timeout may be observed while playing RoadCraft on Radeon™ RX 7000 series products.
• Purple screen may be displayed when using an HP Reverb G2 headset with SteamVR on Radeon™ RX 6000 series graphics products.

Known Issues

• Intermittent application crash or driver timeout may be observed while playing Battlefield™ 6 on AMD Ryzen AI 9 HX 370. AMD is actively working on a resolution with the developer to be released as soon as possible.
• Texture flickering or corruption may appear while playing Battlefield™ 6 with AMD Record and Stream on some AMD graphics products.
• AMD FSR Upscaling and AMD FSR Frame Generation may show as inactive in AMD Software: Adrenalin Edition while playing Battlefield™ 6 when enabled on Radeon™ RX 9000 series graphics products.
• Failure to install may be observed while installing AI Bundle components in some regions with limited access to HuggingFace and GitHub.
• Model flickering or rendering failure may be observed in Maxon Cinema 4D and Blender on Radeon™ RX 7000 series and above graphics products. Users experiencing this issue are recommended to install AMD Software: Adrenalin Edition 26.3.1.
• Intermittent application crash may be observed on some models while running Blender on Radeon™ RX 7000 and above graphics products. Users experiencing this issue are recommended to install AMDSoftware: Adrenalin Edition 26.3.1.
