OptiScaler Tool Expands AMD FSR 4 Support Beyond Official Game List

The open-source utility enables gamers to swap between upscaling technologies like FSR 4, DLSS, and XeSS in supported titles, though functionality remains experimental.

OptiScaler allows users to replace a game's existing upscaling technology (DLSS 2+, FSR 2+, or XeSS) with AMD's FSR 4, provided the game supports one of these options.
FSR 4, AMD's latest upscaling technology, offers significant performance improvements but requires RDNA 4 GPUs like the Radeon RX 9070 and RX 9070 XT.
The tool has been tested successfully on games like Cyberpunk 2077, enabling features like full path tracing at 1440p with over 60 FPS on compatible hardware.
OptiScaler also supports additional features like frame generation and latency-reduction technologies, though some adjustments may be required for optimal use.
As an experimental, unofficial tool, OptiScaler may introduce bugs or stability issues, and it is not endorsed by AMD, Nvidia, or Intel.
