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.
OptiScaler bridges upscaling/frame gen across GPUs. Supports DLSS2+/XeSS/FSR2+ inputs, replaces native upscalers, enables FSR3 FG on non-FG titles. Supports Nukem mod for DLSSG-to-FSR3 FG.
Key aspects of OptiScaler:
Enables usage of XeSS, FSR2, FSR3, FSR4 2 (RDNA4 only) and DLSS in upscaler-enabled games
Allows users to fine-tune their upscaling experience with a wide range of tweaks and enhancements (RCAS & MAS, Output Scaling, DLSS Presets, Ratio & DRS Overrides etc.)
Since v0.7.0+, added experimental DX12 frame generation support with possible HUDfix solution (OptiFG by FSR3)
Supports Fakenvapi integration – enables Reflex hooking and injecting Anti-Lag 2 (RDNA1+ only) or LatencyFlex (LFX) – not bundled 3
Since v0.7.7, added support for Nukem’s FSR FG mod dlssg-to-fsr3, only supports games with native DLSS-FG – not bundled 3
