About

OptiScaler is a tool that lets you replace upscalers in games that already support DLSS2+ / FSR2+ / XeSS (1), as well as manage frame generation in already mentioned games (either by replacing existing FG options or enabling it in DX12 games through experimental OptiFG). It also offers extensive customization options for all users, including those with Nvidia GPUs using DLSS.

CAUTION

• []We've been informed about some FAKE websites presenting themselves as OptiScaler team, so we would like to strongly highlight that we DO NOT HAVE an official website![/]

  []We DON'T have an official manager app, so please be careful when downloading or using them![/]

  []Only LEGIT places are this Github, our Discord server and Nitec's NexusMods page.[/]

  []OptiScaler is FREE, any kind of monetary requirements are scams![/]

  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, albeit requires manually providing nvngx_dlss.dll).

  Key aspects of OptiScaler:

  • []Enables usage of XeSS, FSR2, FSR3, FSR42 (officially, RDNA4 only) and DLSS in (temporal) 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)[/]

    []Supports Fakenvapi integration - enables Reflex hooking and injecting Anti-Lag 2 (RDNA1+ only), LatencyFlex (LFX) or XeLL (Intel only) - bundled since 0. 9[/]

    []Since v0. 7. 7, added support for Nukem's FSR3-FG mod dlssg-to-fsr3, only supports games with native DLSS-FG - bundled since 0. 9[/]

    []Since v0. 7. 8, added ASI plugin loading support (disabled by default (LoadAsiPlugins= in INI), loads from customisable folder, default plugins)[/]

    []New project - OptiPatcher - an ASI Plugin for OptiScaler for enabling DLSS and DLSSG inputs without spoofing in supported games.[/]

    []Since v0. 7. 8, OptiScaler is now automatically applying certain game patches for a better out-of-the-box experience[/]

    []Since v0. 9. 0, separated FG Inputs and Outputs, added XeFG and FSR4-FG support, as well as bundled Fakenvapi and Nukem's FSR3-FG mod[/]
