---

Epic Games Patcher

You obviously need to skip this mod if you have the Steam or GOG version of the game.

Installation instructions:

• Main Files - Epic Games Patcher (Manual download).
  1. From the downloaded archive, extract everything to the game's Root folder.
  2. Double-click on Patcher.exe to run it.
  3. A command prompt window will open and after processing it should say Press any key to continue...
  4. Close the command prompt and a file named FalloutNV_backup.exe should appear in the game's Root folder.

Downgrades the Epic Games EXE for xNVSE and mod support.

xNVSE (Script Extender)

Installation instructions:

• Main Files - New Vegas Script Extender (xNVSE) (Manual download).
1. From the downloaded archive, extract everything to the game's Root folder.

Despite its name, nvse_steam_loader.dll is still needed with the GOG version of the game.

If you do not know what the Root folder is, read the Key Terminology section from the Setup page.

2. After proper install, your Root Folder should look like this:
   

An updated version of the original NVSE, which extends the scripting capabilities of the game.

FNV BSA Decompressor

Installation instructions:

• Main Files - FNV BSA Decompressor (Manual download).
  1. Extract the archive into the Downloads folder
  2. From the extracted archive, 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.

     Epic Games version does not create any keys! You need to select the game folder manually!

  4. Click Decompress, wait for the process the finish, then exit the program once finished.
  5. You can now delete files created in the step 2.

Decompresses BSA files to reduce loading times and stuttering. Can also fix certain sound effects not playing.

Ultimate Edition ESM Fixes

Installation instructions

• Main Files - Main Files - Ultimate Edition ESM Fixes (Manual download).
  1. Extract the archive into the Downloads folder
  2. Click the button next to the profiles bar and select Open Mods folder.
  3. Create an empty folder called Fixed ESMs inside of the Mods folder.
  4. From the extracted archive, run Installer.exe.
  5. The Fallout: New Vegas path should be filled by default (root folder). If it isn't, close the program and re-run your game launcher to generate the required registry key.

     Epic Games version does not create any keys! You need to select the game folder manually!

  6. Click Browse next to the ESM Fixes path field, then choose the Fixed ESMs folder you just created.

Optimizes and fixes thousands of records across the base game and DLC plugins to increase performance and stability.

FNV 4GB Patcher

This is required for both Steam & GOG users! The 4GB Patch included with the GOG release is obsolete as it lacks NVSE integration.

Epic Games Store users already have this patch thanks to the Epic Games Patcher.

Installation instructions:

• Main Files - 4GB Patcher (Manual download).
  1. From the downloaded archive, extract the .exe file to the game's Root folder.
  2. Double-click on FNVpatch.exe to run it.
  3. A command prompt window will open and should say FalloutNV.exe patched!
  4. Close the command prompt and a file named FalloutNV_backup.exe should appear in the game's Root folder.

Allows the game to use 4GB of RAM and makes the default executable auto-load NVSE, which is safer than using the NVSE executable.

New Vegas Heap Replacer

Installation instructions:

• Main Files - NVHR (Manual download).
  • From the downloaded archive, extract everything to the game's Root folder.

Replaces the game's heap management system with a much faster version, which can lead to large performance gains.

1. Click the button at the top of MO2 and select INI Editor.
2. Select the FalloutCustom.ini tab, which should be blank.
• Make sure you are in the FalloutCustom.ini tab and NOT the Custom.ini tab.
3. Paste in the following:
[Audio] ; Enables additional worker thread for minor performance improvement bMultiThreadAudio=1 ; Disables debug logging to save memory and CPU time bUseAudioDebugInformation=0 ; Increase audio file cache size to reduce loading stutter iAudioCacheSize=16384 iMaxSizeForCachedSound=2048 [BackgroundLoad] ; Forces cell unload on fast travel to lessen memory usage bSelectivePurgeUnusedOnFastTravel=1 ; Reduces stutter when loading multiple NPCs bBackgroundLoadLipFiles=1 [Controls] ; Disables mouse acceleration in menus ; Game does not have mouse acceleration for the camera fForegroundMouseAccelBase=0 fForegroundMouseAccelTop=0 fForegroundMouseBase=0 fForegroundMouseMult=0 [Display] ; Enables Fullscreen mode for the best performance in D3D9 ; Refer to the Performance Guide for more info bFull Screen=1 ; V-Sync control (the Launcher setting doesn't work) ; 0 = Off, 1 = On iPresentInterval=1 ; Forces highest texture quality so the game won't crash if you had it set to anything lower iTexMipMapSkip=0 ; Disables actor shadows due to their low visual impact and high performance cost bDrawShadows=0 iActorShadowCountInt=0 iActorShadowCountExt=0 ; World FOV fDefaultWorldFOV=75.0000 ; 1st person FOV fDefault1stPersonFOV=55.0000 ; Pip-Boy and terminal FOV fPipboy1stPersonFOV=47.0 [General] ; Forces faster cell unload to lessen memory usage bPreemptivelyUnloadCells=1 ; Enables multithreaded AI ; Values above 3 don't change anything iNumHWThreads=3 [Grass] ; Increases grass draw distance fGrassStartFadeDistance=11200 ; Ensures that 3.0 Vertex Shader is used. ; Allows drawing more grass with better performance b30GrassVS=1 [PipBoy] ; Fixes flicker when opening Pip-Boy when its light is on fLightEffectFadeDuration=400

It is highly recommended to avoid changing any other INI settings not in the guide and to avoid using tools like BethINI.
You will realistically not need any other tweaks than the ones already in the guide.

Testing Utilities

1. Restart your PC (otherwise some plugins may fail to load).
2. Launch the game using the New Vegas option in MO2 (not the NVSE option).

3. If you see a black console window appear, it means NVHR is working.

• If not, xNVSE is installed incorrectly.
6. Next, enter GetIsLAA and the console should print GetIsLAA >> 2
