An unreleased version of AMD's FidelityFX Super Resolution 4 (FSR 4) with INT8 support was reportedly leaked on October 18, 2025, revealing potential for the advanced upscaling technology to be compatible with a wider range of older graphics cards and consoles. This alternate variant is said to utilize INT8 machine learning instructions, in contrast to the FP8 rendition in the official RDNA 4-exclusive release, which could significantly broaden the technology's adoption across hardware that lacks the newer capabilities. The leak originated from a version of the FSR 4 source code that was mistakenly uploaded to GitHub by AMD. This development, if confirmed, could have a notable impact on the gaming market by bringing modern upscaling benefits to a larger audience of gamers with older hardware, potentially increasing the appeal of AMD's technology for game developers.
