For Nvidia

Step-by-step installation:

1. Extract all of the Optiscaler files by the main game exe

[!IMPORTANT] (for Unreal Engine games, look for the win_shipping.exe in one of the subfolders, generally <path-to-game>\Game-or-Project-name\Binaries\Win64 or WinGDK\, ignore the Engine folder)

Example paths - Expedition 33\Sandfall\Binaries\Win64, Jedi Survivor\SwGame\Binaries\Win64, Cyberpunk 2077\bin\x64, HITMAN 3\Retail, Warhammer 40,000 DARKTIDE\binaries, The Witcher 3\bin\x64_dx12

2. Rename OptiScaler's OptiScaler.dll (for old versions, it's nvngx.dll) to one of the supported filenames (preferred dxgi.dll, but depends on the game)$^1$

[!NOTE] For FSR2/3-only games that don't have DLSS (e.g. The Callisto Protocol or The Outer Worlds: Spacer's Choice Edition), you have to provide the nvngx_dlss.dll in order to use DLSS in Optiscaler - download link e.g. TechPowerUp or Streamline SDK repo

For AMD/Intel

Step-by-step installation:

1. Extract all of the Optiscaler files by the main game exe

[!IMPORTANT] (for Unreal Engine games, look for the win_shipping.exe in one of the subfolders, generally <path-to-game>\Game-or-Project-name\Binaries\Win64 or WinGDK\, ignore the Engine folder)

Example paths - Expedition 33\Sandfall\Binaries\Win64, Jedi Survivor\SwGame\Binaries\Win64, Cyberpunk 2077\bin\x64, HITMAN 3\Retail, Warhammer 40,000 DARKTIDE\binaries, The Witcher 3\bin\x64_dx12

2. Rename OptiScaler's OptiScaler.dll (for old versions, it's nvngx.dll) to one of the supported filenames (preferred dxgi.dll, but depends on the game)$^1$

3a. Either locate the nvngx_dlss.dll file (for UE games, generally in one of the subfolders under Engine/Plugins), create a copy, rename the copy to nvngx.dll and put it beside Optiscaler

3b. OR download nvngx_dlss.dll from e.g. TechPowerUp or Streamline SDK repo if you don't want to search, rename it to nvngx.dll and put it beside Optiscaler

[!TIP] [1] Linux users should add renamed dll to overrides:

WINEDLLOVERRIDES=dxgi=n,b %COMMAND%

[!IMPORTANT] Please don't rename the ini file, it should stay as OptiScaler.ini.

[!NOTE]

OptiScaler supports these filenames:

  • dxgi.dll
  • winmm.dll
  • d3d12.dll (from 0.7.7 nightlies)
  • dbghelp.dll (from 0.7.7 nightlies)
  • version.dll
  • wininet.dll
  • winhttp.dll
  • OptiScaler.asi (needs ASI loader)
