OptiScaler is a tool that lets you replace upscalers in games that already support DLSS2+ / FSR2+ / XeSS, now also supports enabling frame generation (through OptiFG or Nukem’s dlssg-to-fsr3).
While previously only DLSS2+ inputs were supported, newer versions also added support for XeSS and FSR2+ inputs (with some caveats 1 ). For example, if a game has DLSS only, the user can replace DLSS with XeSS or FSR 3.1 (same goes for an FSR or XeSS-only game). It also offers extensive customization options for all users, including those with Nvidia GPUs using DLSS.
Enables usage of XeSS, FSR2, FSR3, FSR4 2 and DLSS in upscaler-enabled games.
OptiScaler implements the necessary API methods of DLSS2+ & NVAPI, XeSS and FSR2+ to act as a middleware. It interprets calls from the game and redirects them to the chosen upscaling backend, allowing games using one technology to use another one of your choice.
