With the Radeon RX 9000 series, AMD launched updated gaming upscaling technology<\/a>. FSR4 uses artificial intelligence for the upscaling step for the first time, which should improve image quality. However, there’s the usual problem of not all games supporting these technologies. Now, a surprisingly capable solution has emerged\u2014the OptiScaler tool, which can “force” the new FSR into a large group of games that don\u2019t natively support it.<\/p>\n

Back in the days of FSR 2 already, mods have quickly appeared<\/a> that unofficially added support for AMD\u2019s upscaling to selected games by converting the calls of Nvidia\u2019s DLSS upscaling interface, enabled by the fact that in principle, all these technologies work very similarly. Now, a mod called OptiScaler has appeared on GitHub, which does this more generally and can “swap” upscaling in various games. Currently, it allows FSR4 to be added to games that don\u2019t have official support (and not even FSR 3.1 support, with allows FSR4 to be upgraded into games officially by AMD drivers). But the possibilities don\u2019t end there\u2014OptiScaler can universally replace these technologies, making it useful for users of all brands.<\/p>\n

The tool can also add Intel\u2019s XeSS upscaling to games implementing DLSS. In addition to the new FSR4, which currently only works on Radeon RX 9000 cards with RDNA 4 architecture<\/a>, it also supports the older FSR 3.1, which is universally compatible. However, it can also dot he reverse and replace FSR with Nvidia\u2019s DLSS upscaling (which will then only run on GeForce RTX 2000 and newer graphics cards). It works by acting as a wrapper inserted between the game and the upscaling, implementing the necessary APIs to make the chosen technology function.<\/p>\n

Since this is work byl game hacking, OptiScaler naturally has its limitations, and various games may have compatibility issues. However, the tool has successfully managed to enable FSR4 in Cyberpunk 2077, where, given Nvidia\u2019s sponsorship of the game, it\u2019s questionable when or if official support will ever arrive.<\/p>\n
