A new AMD FSR 4.1 DLL has just quietly surfaced on the internet, prompting plenty of Radeon owners to download the file before AMD could wipe it from its own website. Despite the chip maker\u2019s best efforts to contain it, this new iteration of the upscaler is now widespread, as enthusiasts attempt to unpack its improvements over FSR 4.<\/p>\n
Following a prior FSR 4.1 leak<\/a> in February, this file originates from AMD directly and presumably contains improvements to the machine learning algorithm. Unfortunately, the download page did not highlight any changes relative to earlier versions, nor specific comparisons to FSR 4. As such, it\u2019s up to pixel peepers to manually conclude what upgrades this version offers.<\/p>\n However, we do know that this file arrives as part of the wider Radeon Software suite. Specifically, it replaces the existing FSR 4.0.3 DLL that you can use to upgrade FSR 3.1 games via driver injection. Upon successful replacement, games will reflect this change in their settings menus with an FSR 4.1 option.<\/p>\n<\/p>\n Tech YouTube channel Hardware Unboxed put FSR 4.1 under the proverbial microscope using a Radeon RX 9070 XT<\/a>, focusing on the image quality using the upscaler\u2019s Performance mode at 4K, where it upscales a 1080p source image. Naturally, presets that tip the scales in favour of image quality over performance by increasing the base resolution should net superior results.<\/p>\n The most noticeable improvement that FSR 4.1 brings to the table, based on Hardware Unboxed\u2019s analysis, is greater retention of texture detail in motion via reduced smearing. This provides a sharper image overall, relative to FSR 4.0.3, but AMD\u2019s tech remains softer to the eye than Nvidia DLSS 4.5<\/a>.<\/p>\n However, FSR 4.1\u2019s change in approach can result in an increase of shimmering artefacts. This is particularly noticeable on foliage edges and thin lines, with leaves, grass, and chain-link fencing appearing sharper but more unstable relative to FSR 4.0.<\/p>\n In a small handful of games, Hardware Unboxed didn\u2019t find any notable performance differences between FSR 4.0.3 and 4.1 across several upscaling modes. It\u2019s possible that a wider set of tests could reveal differences in frame rates, but for now it seems that AMD is primarily focusing on image quality.<\/p>\n It\u2019s important to stress that this isn\u2019t necessarily the final form that FSR 4.1 will take, as we don\u2019t know when AMD plans to officially launch the new version of its upscaler. This does leave time for AMD to further iterate and improve the tech, possibly resolving some of the stability issues described above, but there\u2019s no guarantee this will come to pass.<\/p>\n In lieu of an official release date, I suspect we\u2019ll see FSR 4.1 debut at Computex 2026 in June at the latest. We\u2019ll be attending the show, so make sure you\u2019re following Club386 on Google News and set us as one of your Google Preferred Sources so you don\u2019t miss a beat.
