  5. In Installation Location select an empty folder that is NOT the following:

Post-Install Steps

  1. In your Installation Location, open the Tools folder, then open the 4GB Patcher folder.
  2. Copy the .exe file to the game's Root folder.
  3. Right-click on FNVpatch.exe and select Run as administrator.
  4. A command prompt window will open and should say FalloutNV.exe patched!
  5. Close the command prompt and a file named FalloutNV_backup.exe should appear in the game's Root folder.
  6. In your Installation Location, open Mod Organizer 2.
  7. IMPORTANT: If you are running the game at a resolution higher than 1080p, enable the Texture Modding and High Res Preset under the Utilities separator!
  8. Now you can play the game through the New Vegas option in the top right:
  9. Run New Vegas through MO2
The Viva New Vegas Wabbajack already comes with all plugins decompressed and the VNV FNVLODGen Output.

Optional Steps

FPS Limiter

Follow the limiter section of the Performance Guide in order to massively reduce your latency (this is highly recommended because the Wabbajack only comes with VSync as default, which is not meant to be used as a limiter but we cannot provide a pre-configured one).


BSA Decompressor will give you slightly better performance and faster loading times at a small disk space cost.
  1. In the same Tools folder as before, open the BSA Decompressor folder.
  2. Run FNV BSA Decompressor.exe.
  3. The Fallout: New Vegas and Decompressed Archives paths should be filled by default (root folder and data folder respectively). If they aren't, close the program and re-run your game launcher to generate the required registry key.
  4. Click Decompress, wait for the process the finish, then exit the program once finished.


DXVK is mainly used to improve performance in CPU-limited scenarios, which are the main cause of low FPS in this game.
  1. Read the mod description available here.
  2. Once you know if your GPU supports DXVK and what version to use, enable the correct DXVK for your setup under the Utilities separator.


Improves performance by optimizing the game's heap.
  1. Head to the Tools folder, then the NVHR folder.
  2. Take all files and drag them to the game's root folder.

Updating the List

  1. Verify files on Steam or GOG Galaxy.
  2. Reinstall the list from the Wabbajack tool and enable the "Overwrite Installation" checkbox.
  3. Reapply the 4GB Patcher and optionally the BSA Decompressor.
