![OptiScaler Installer 1.0.6.1 [Now with FSR4 INT8 installer]](https://www.cybermania.ws/wp-content/uploads/OptiScaler.png)
OptiScaler is a tool that lets you replace upscalers in games that already support DLSS2+ / FSR2+ / XeSS ( 1 ), now also supports enabling frame generation in those same games (through Nukem’s dlssg-to-fsr3 or OptiFG). It also offers extensive customization options for all users, including those with Nvidia GPUs using DLSS.

- Install from stable, alternate release source, or local OptiScaler archive (.7z).
- GPU vendor settings and OptiFG/Nukem frame generation options.
- Add-ons: Fakenvapi, Nukem FG DLL, nvngx_dlss.dll, ReShade, Special K, ASI plugins.
