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.
