AMD's 4th Generation FidelityFX Super Resolution image upscaling technology with frame generation is a very promising feature of the company's latest Radeon RX 9000-series, but for now it is officially supported by a limited number of games. Nonetheless, modders have found a way to add FSR 4 to any game that supports Nvidia's DLSS2 or newer or Intel's XeSS, reports VideoCardz.
To do so, they invented the OptiScaler app that can enable FSR 4 in all games supporting Intel's XeSS and/or Nvidia DLSS2 or newer machine learning-based upscaling technologies. Additionally, OptiScaler adds support for frame generation and anti-lag features, enhancing gaming performance in titles that for now lack these options officially.
