Epic Games Patcher

Epic Games Downgrader

A patcher / downgrader tool for the epic games version of Fallout NV that allows use of NVSE.

Features

• []Downgrades the game to the steam version which is widely supported by other mods, most notably NVSE.

  []Makes the game 4GB aware

  []Automatically loads NVSE when using FalloutNV.exe to start the game (if NVSE is installed)

  Compatibility

  • []The patcher supports latest Epic Games version of the game.

    Installation

    • []Unpack the contents of the archive to 'Fallout New Vegas English' folder and run Patcher.exe.

      []You will see black console window with a log of the process. No input is required, but it will tell you if any error has occurred.

      []When it's done and you see "Patching completed successfully" printed, you can close the window and proceed to installing other mods, such as NVSE.

      []Start the game through Epic's launcher, or any supported mod manager, but don't use nvse_loader.exe. Forget it exists, it's safe to delete it.

      Notes

      • []This partially removes Epic Games integration (including achievements - I may try and restore them in the future)

        []Do not use nvse_loader.exe to run the game with NVSE after running the patcher. Launch through Epic instead, it will auto-load NVSE.

        []The Steam version of the game was compiled without optimisations enabled so performance is worse, though a lot can be regained by following the performance guide in VNV.

        []If the patcher gives "Invalid executable" error, verify your game files on Epic and make sure the game is up to date.

        []This is a binary patcher that does not redistribute any copyrighted files or facilitate piracy in any way. A legitimate copy of the game is required to use it.
