OVERVIEW

F4SE plugin which implements full support for DLSS 4 and FSR 3.1 upscaling for all game versions. DLAA support for ENB.

  • Upscaling reconstructs lower resolutions to the native resolution using advanced algorithms, improving image quality and performance.
  • When using ENB, only DLAA is supported.
  • Includes a modification to screenspace reflections to improve their quality.
  • Default settings improve performance by at least 15%.
  • Upscaling is automatically disabled in the pipboy menu and 3D interfaces to retain clarity. This increases VRAM usage slightly as it must support rendering the game at two different resolutions.

MOD CONFIGURATION MENU

An MCM settings menu is provided to tweak upscaling in-game and give helpful information:

OPTISCALER

You can use Optiscaler to add support for FSR 4 and XeSS when using the DLSS Upscale Method Preference. This will also unlock the usage of FSR 3.1 Native AA when using ENB.

To use Optiscaler, download the latest release and extract to your root directory, next to Fallout4.exe. Then, run the setup file to install the mod as dxgi.dll.
