What is OptiScaler?

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.

Tip

For example, if a game has DLSS only, OptiScaler can be used to replace DLSS with XeSS or FSR 3.1 (also works for FSR2-only games, like The Outer Worlds Spacer's Choice).

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

Important

Always check the Wiki Compatibility list for known game issues and workarounds. Also please check the OptiScaler known issues at the end regarding RTSS compatibility. A separate FSR4 Compatibility list is available for community-sourced tested games. [3] For not bundled items, please check Installation.
