How to Use a Modding Tool to Enable AMD’s FSR 4 on Any Game, Including Cyberpunk 2077

Gamers seeking to leverage AMD’s FSR 4 technology have exciting news: it can now be utilized across various games, as long as those titles support either DLSS or XeSS upscalers. This has been made possible thanks to the innovative contributions from the modding community.

Introducing OptiScaler: An Open-Source Solution for FSR 4 Access

The launch of AMD’s FSR 4 technology has generated significant anticipation, especially given the impressive performance improvements over the previous FSR 3.1 version. However, the initial exclusivity of FSR 4 to the Radeon RX 9070 series GPUs and the limited number of supported titles left many gamers disappointed. Fortunately, modders have stepped up to fill this gap by developing OptiScaler, a revolutionary tool that allows users to experience FSR 4 in any compatible game, provided those games are integrated with DLSS 2+ or Intel’s XeSS.

How OptiScaler Transforms Game Upscaling

OptiScaler functions as a middleware that bridges various upscaling technologies with gaming titles. This innovative software reroutes upscaling requests to compatible technologies, utilizing API methods effectively. By emulating the functionalities of DLSS, XeSS, and FSR, OptiScaler ensures that games continue to operate as if they were originally employing the intended upscaling method, a fascinating technical feat.

Performance Insights with OptiScaler

A pivotal question arises regarding the performance levels achieved through OptiScaler. User @highyieldYT showcased OptiScaler in action with Cyberpunk 2077, demonstrating that FSR 4 could be effectively applied. The user reported achieving over 60 FPS at 1440p settings utilizing a Radeon RX 9070 XT. Notably, Cyberpunk 2077 does not officially support FSR 4 or even FSR 3.1, highlighting OptiScaler’s impressive capabilities.
