FSR 4.1 has been released for AMD’s RDNA3 GPUs, significantly improving image quality and stability over the previous FSR 3.1 by using INT8 instructions, delivering near-parity with RDNA4’s FP8 version. Although slightly more demanding performance-wise, this update revitalizes RDNA3 hardware with sharper visuals and better artifact handling, marking a major upgrade despite AMD’s delayed release.
FSR 4.1 has finally been released for AMD’s RDNA3 RX7000 series GPUs, marking a significant upgrade from the previous FSR 3.1. This new version uses INT8 instructions, enabling it to run on RDNA3 hardware despite initial claims that FSR4 would be exclusive to RDNA4 due to its reliance on FP8 instructions. The update was long-awaited, as FSR 3.1 was widely regarded as subpar, especially at 1440p resolution, with poor image quality and stability issues. AMD’s accidental leak of the FSR4 source code in 2025 revealed the INT8 version, confirming that a better upscaling solution was possible on RDNA3, but AMD delayed its official release for over a year.
The improvements in image quality with FSR 4.1 on RDNA3 are dramatic. Compared to FSR 3.1, FSR 4.1 delivers much sharper, more detailed visuals with significantly reduced blur and better handling of challenging elements like foliage, water, and transparent effects. Stability is also greatly enhanced, with fewer shimmering and aliasing artifacts, making FSR 4.1 performance mode often superior to FSR 3.1 quality mode. These gains are especially pronounced at 1440p, where FSR 3.1 was previously almost unusable, making FSR 4.1 a transformative upgrade for RDNA3 gamers.
When comparing FSR 4.1 INT8 on RDNA3 to the FP8 version on RDNA4, the two are nearly indistinguishable in image quality. Across multiple games and scenarios, the INT8 version delivers virtually the same sharpness, stability, and artifact handling as the FP8 version. Minor edge cases show slight quality reductions for the INT8 version at lower render resolutions, but these differences are subtle and unlikely to be noticed during typical gameplay. This parity means RDNA3 users are effectively getting the full FSR 4.1 experience despite the older hardware.
Performance-wise, FSR 4.1 on RDNA3 is somewhat more demanding than FSR 3.1, resulting in slightly lower frame rate boosts. For example, in Cyberpunk 2077 at 4K, FSR 4.1 provides a substantial but smaller performance uplift compared to FSR 3.1. However, considering the significant image quality improvements, this trade-off is worthwhile. In some games like Horizon Zero Dawn, the performance gains are modest, but the enhanced visual fidelity makes FSR 4.1 the better choice overall. The performance and quality balance positions FSR 4.1 as a strong competitor to Nvidia’s DLSS 4.5, especially at 1440p.
Despite the clear benefits of FSR 4.1 on RDNA3, AMD’s delay in releasing this update has been a sore point. Nvidia has consistently provided upscaling improvements to its GPUs across generations promptly, while AMD left RDNA3 users stuck with outdated technology for over a year. This lack of timely software support has hurt AMD’s reputation among Radeon users. Nonetheless, the arrival of FSR 4.1 INT8 is a major win for RDNA3 owners, breathing new life into their GPUs. AMD’s future support for older architectures, including RDNA2, remains uncertain, but this release is a positive step forward.
