AMD FSR 4.1 support arrives early for RDNA 3 GPUs, bringing AI upscaling to RX 7000 series

AMD brings official FSR 4.1 support to RX 7000 series GPUs -- INT8 model now available in 300+ games, RDNA 3 APUs also getting FSR 4.1 soon

Last month, AMD officially announced FSR 4.1 for older RDNA 2 and RDNA 3 hardware, with the RX 7000 series set to receive FSR 4.1 support in July. Well, Christmas has come early as FSR 4.1 is out now for RDNA 3 desktop GPUs, a few days before it was originally supposed to launch. It's available natively in over 300 games, and all you need to do is update your GPU drivers inside AMD Adrenaline software to unlock the latest upscaler. * ASRock Challenger Radeon RX 9070 : now $599 at Newegg FSR 4.1 for the RX 7000 series is based on INT8 code that differs from the FP8 instruction set that the RX 9000 series uses. Technically speaking, only RDNA 4 has the hardware required for FSR 4.1 to work optimally, while making it backwards compatible with previous generations requires a lot of tuning and falling back on older instructions that incur a slight performance loss in exchange for better visual quality. AMD is confident that its in-house optimizations deliver better results than community efforts, as the video embedded above shows official FSR 4.1 achieving higher frame rates in Forza Horizon 6 and Crimson Desert versus FSR 4.0.2c. That version is built from leaked code that came out last year and has since served as the foundation of Optiscaler mods that force-inject FSR 4 by making the game think it's actually DLSS. The biggest difference will still be seen against native rendering -- playing Crimson Desert at 4K, an RX 7900 XTX only managed about 43 FPS on average, while FSR 4.1 bumped that up to 64 FPS. That's nearly a 50% improvement, while looking considerably better than FSR 3.1 and remarkably close to FSR 4.1 on the RX 9000 series. Sure, FSR 3.1 could probably net a few more FPS, but the image quality won't be as sharp. AMD also confirmed it's working on "lightweight machine learning models" to bring FSR 4.1 to RDNA 3 APUs, which should extend support to a wide range of devices. For instance, the Z1 Extreme chip inside Valve's Steam Deck is based on RDNA 3 architecture. Phoenix Point and Hawk Point silicon, i.e., Ryzen 7040, Ryzen 8000(G), Ryzen 8040, and Ryzen 200 series, also rely on RDNA 3 graphics. RDNA 3.5 is an extension of RDNA 3, and AMD pushed back against it, not receiving FSR 4.1 just this month. If we assume this announcement also counts RDNA 3.5, then expect FSR 4.1 to also come to Ryzen AI 300 and Ryzen AI 400 series, along with Ryzen AI Max processors. AMD's current-gen Ryzen Z2 family for handhelds is also based on RDNA 3.5. For now, though, FSR 4.1 seems limited strictly to RDNA 3 desktop GPUs. Support for older RDNA 2-based graphics cards is expected in early 2027, even though the community has interchangeably used INT8 mods for both the RX 6000 and RX 7000 series. Expect a bigger performance tradeoff on RDNA 2 compared to RDNA 3, which is what the company is likely trying to minimize in the months leading up to its launch. Nonetheless, it's exciting to see AMD at least try to catch up to Nvidia in terms of its upscaler support.

AMD says FSR 4.1 on RDNA 3 will feature no quality loss

AMD's FSR 4.1 is coming to more Radeon gamers, starting with desktop RDNA 3 support arriving next month, which brings the vastly superior AI-powered version of FSR to the Radeon RX 7000 Series of graphics cards. Up until now the technology has been exclusive to the latest RDNA 4 generation and cards like the Radeon RX 9070 XT, but that's about to change. Sitting down with AMD's Chief Software Officer, Andrej Zdravkovic, and AMD's Senior Director of Software, Terry Makedon, TechPowerUp has learned that the version of FSR 4.1 that will debut for RDNA 3 GPUs will arrive with no quality loss when it comes to the final image displayed on screen. This is good news because AMD has had to rebuild and optimize FSR 4.1 to run on RDNA 3's first-gen AI hardware, which uses INT8 data, rather than the more efficient FP8 used on RDNA 4, which served as the basis for FSR 4. According to the report, AMD has had to modify the underlying model to support RDNA 3, but the end result for image quality will be the same. For gamers with cards like the Radeon RX 7800 XT and previous-gen flagship Radeon RX 7900 XTX, FSR 4.1 support will unlock a new level of performance and image fidelity, especially when gaming at higher resolutions. As for bringing FSR 4.1 to RDNA 2 and GPUs from the Radeon RX 6000 Series, it's a lot more complicated, hence the 2027 release window. Apparently, to get FSR 4.1 running on RDNA 2, which lacks dedicated AI hardware and accelerators, AMD's solution will rely on the GPU's Stream Processors to handle upscaling. And with that, it will require a lot more optimization to ensure that FSR 4.1 doesn't introduce additional latency or blow out render times.

AMD Reportedly Enables FSR 4 On RDNA 3 GPUs Through Valve Proton Experimental

AMD's latest upscaling technology won't just be exclusive to RDNA 4 GPUs as we know, and the latest update includes Linux as well. Valve Proton Experimental Reportedly Brings FSR 4 Support to AMD RDNA 3 GPUs AMD isn't just working on bringing its latest FSR 4 branch to older GPUs, but is also working on enabling it on the Linux operating system on a previous-generation GPU family. According to the latest report, Valve's Proton Experimental branch now includes support that enables FSR 4 to run on the RDNA 3 (Radeon RX 7000 series) GPUs through an unofficial implementation. The feature has arrived through updates to VKD3D-Proton, the DirectX 12-to-Vulkan translation layer used by Proton and SteamOS. As spotted by @SadlyItsBradley, the recent VKD3D-Proton changes indicate that support for FSR 4 has been added to the translation layer. The DLL file "amdxcffx64.dll" has been added to Valve's Proton Experimental files, enabling the latest AI upscaling technology to run on Linux on RX 7000 series GPUs, including systems such as Steam Machine to upgrade from FSR 3 to FSR 4. This comes right after AMD announced official FSR 4.1 support on RX 7000/RX 6000 series. The support comes next month on the RDNA 3 GPUs, more than a year after FSR 4 debuted alongside the RX 9000 series GPUs. The RX 7000 series will utilize the INT8 FSR 4 version, unlike the model used on the RX 9000 series. AMD confirmed recently that despite using a different FSR 4.1 model on the RDNA 3 GPUs, the final result will be on par with the FSR 4.1 model on the RX 9000 series. For Linux gamers using the Radeon RX 7000 series graphics cards, Proton Experimental could provide an early preview of FSR 4 functionality ahead of AMD's official rollout. However, the feature remains experimental, so users should expect varying levels of compatibility and performance depending on the game.

AMD Confirms Different FSR 4.1 Model For RDNA 3 GPUs; Delayed Support On RDNA 2 Is Due To Significant Optimization Needs

AMD explains why it needs time to add support for FSR 4.1 on RDNA 2, aka Radeon RX 6000 GPUs, and what are the current challenges it is facing. AMD Says RDNA 3 Uses Different FSR 4.1 Model Than RDNA 4, But the End Result is On Par With the Latter There are reasons behind delayed support for FSR 4.0/4.1 on the older Radeon cards, which is why AMD took its time to bring the new upscaling technology on previous-gen cards. AMD has faced a lot of criticism for not bringing FSR 4.0/4.1 on RDNA 3 and RDNA 2 GPUs, despite the fact that the INT8 DLL files existed for adding the new upscaler, which has proven to work flawlessly through workarounds and various third-party tools. Nearly a year after FSR 4.0's launch alongside the RDNA 4 GPUs, AMD finally came out announcing FSR 4.1 support for older graphics cards such as the RDNA 3 and RDNA 2 families. While RDNA 3 will get FSR 4.1 support in the next month, AMD explains why it is taking more time for FSR 4.1 to release for RDNA 2 GPUs. As far as the models are concerned, AMD confirmed to Techpowerup that the company is using a different model of FSR 4.1 than on RDNA 4 GPUs. However, the difference will be negligible as the final result will be on par with FSR 4.1 working on RDNA 4 GPUs. The reason for using a different model of FSR 4.1 on RDNA 3 is the absence of FP8 (8-bit floating-point) support. RDNA 3 only supports INT8 (8-bit Integer data type), and it's necessary to requantize the model so it runs efficiently with the INT8 data type instead of FP8. Simply converting FP8 values to INT8 can cause artifacts, which is why conversion is necessary. As for RDNA 2, the microarchitecture lacks AI accelerates to support FSR 4.1 upscaling and relies totally on the Stream Processors. This is why AMD needs time for optimizations to ensure FSR 4.1 can run efficiently on RDNA 2 while consuming fewer shader cycles, which is currently a major challenge. At the time of writing, the FSR 4.1 support is scheduled to arrive on RDNA 2, aka Radeon RX 6000 GPUs, in early 2027.
