OptiScaler allows users to replace in-game upscalers like DLSS 2+, FSR 2+, and XeSS with alternative technologies, even if the game was originally designed to support only one of them.

Features

Broad Compatibility

Works across popular game engines and supports community mods, giving more flexibility and integration in diverse gaming setups.

Better Performance

Works across popular game engines and supports community mods, giving more flexibility and integration in diverse gaming setups.

Easy Switching

Switch between DLSS, FSR, or XeSS quickly without complex setup – ideal for testing or optimizing visuals per game.

Frame Generation

Enables frame generation even in unsupported games using third-party tools like OptiFG or dlssg-to-fsr3 for smoother gameplay.

How OptiScaler Works

OptiScaler Frame Generation

Boosts FPS and smoothness using FSR 3 or DLSS-based frame generation.

Boost FPS with Smarter Upscaling

OptiScaler increases performance by replacing demanding upscalers with optimized alternatives, delivering higher FPS without compromising visual quality.

Extend GPU Life with OptiScaler

OptiScaler reduces GPU strain by replacing heavy native rendering with efficient upscaling. Keeps older GPUs relevant in modern games with smoother, faster performance.

Enhance Hardware Compatibility

Compatible with AMD, NVIDIA, and Intel GPUs (upscaler-specific), making it a flexible choice for gamers using varied systems.

System Requirements for OptiScaler

Compatible Graphics Cards

OptiScaler requires an AMD RDNA 4 GPU, such as the RX 9700 XT or any card from the RX 9000 series. These GPUs are essential for enabling FSR 4 and frame generation features. Older AMD cards, as well as NVIDIA or Intel GPUs, may not support all functions.

Upscaler Input Compatibility

The target game must support modern upscaling technologies. OptiScaler works by replacing existing upscalers like DLSS 2, FSR 2, or Intel XeSS. Games without these features cannot be modified using OptiScaler.

Supported Game APIs

Only works with games running on DirectX 11 or DirectX 12. Games that use the Vulkan graphics API are not currently supported by OptiScaler.

Operating System Requirements

Runs on Windows 10 and Windows 11. A 64-bit version of the operating system is required. Administrator privileges are recommended during setup for proper file integration.

Game Compatibility Conditions

Games must not include anti-cheat software such as Easy Anti-Cheat, BattleEye, or Vanguard. These security systems may block OptiScaler or result in account bans if used in online titles.

Storage and File Access

Requires local disk access to copy essential DLL files and configuration settings into the game directory. A few megabytes of free space is sufficient, but write permissions are necessary for performance tuning.

What's New

New and improved MAJOR features in 0.9.4:

  • Updated to latest FFX 2.3 SDK/FSR4.1.1 (@FakeMichau, @TheRazerMD, @cdozdil)
  • Updated model/preset hooking for FSR 4.1.1 (@TheRazerMD, @FakeMichau)
  • Fixes the Failed to hook error on both the Driver and SDK upscaler DLL
  • Added FSR 4.1.1 for officially supported cards (@FakeMichau)
  • RDNA 3 desktop GPUs (dGPUs) now have autoenabled Fsr4Update to access the INT8 model
  • RDNA 3/3.5 mobile iGPUs/APUs are not officially supported, neither are other vendors, check below!
  • Try to use Int8 on RDNA3 on Linux when possible (@FakeMichau)
  • Don't link FSR-FG camera struct if it's just all zeros (@FakeMichau)
  • Should fix an issue where driver upgrade FG would fallback to FSR3-FG when using OptiFG
  • Added Fsr4ForceEnableInt8 option for FSR4 incompatible GPUs (@cdozdil). Set this option to true to force enable INT8 on unsupported GPUs - such as RDNA 3/3.5 mobile (iGPU/APU), Intel/Nvidia
  • Do not touch the Fsr4Update= option in OptiScaler.ini, as setting it true on unsupported GPUs will autofallback to FSR3!
  • This does not mean old GPUs (which don't support INT8) will work!
  • Only applies to the shipped SDK upscaler DLL, won't affect the Driver amdxcffx64.dll!
  • RDNA2 Windows users are recommended to continue using FSR 4.0.2c as the driver compiler regression (which causes ghosting etc) is yet to be fixed

Bug fixes

  • Fix FSR3.1 presets dynamic calculation (@cdozdil)
  • Fix for Typeless Hudless resourcess (@cdozdil)
  • Fix dlssg_to_fsr3_amd_is_better.dll check at menu (@cdozdil)
  • Fixed Where Winds Meet MV issues which broke FSR3-FG (@cdozdil)
  • Now all FGs should work properly
  • Added missing Ubisoft game exes to their respective quirks (@TheRazerMD)
  • Splash update (@FakeMichau)
