Utilities

In this section we will install a multitude of required tools and mods. It's very important not to skip anything on this page, with the sole exception of the totally optional Discord Rich Presence.

Utilities Installed Manually​

FNV 4GB Patcher​

Makes Fallout New Vegas 4GB aware and automatically loads xNVSE.

Installation:​

Manual Download the Main File - 4GB Patcher, extract the FNVpatch.exe to the game's Root folder, then right-click it and Run as administrator. Close the FalloutNV.exe patched! command prompt that appears. There should now be a FalloutNV_backup.exe in the game's Root folder.

xNVSE​

Expands the engine and scripting capabilities of Fallout New Vegas, fixing bugs and adding hundreds of new functions.

Installation:​

Manual Download the Main File - New Vegas Script Extender (NVSE) and extract the contents to the game's Root folder. Note that even if you have the GOG version, you still need to include nvse_steam_loader.dll. xNVSE post-install root folder

New Vegas Heap Replacer​

An optimized replacement for the game's heap which will benefit load times, stutter and frame rate.

Installation:​

Manual Download the Main File - NVHR and extract the contents of the archive to the game's Root folder.

NVHR Terminal Window

By default, NVHR will create a terminal window every time the game is launched, letting you know it has loaded successfully. If you would like the terminal to stop appearing, create a file named d3dx9_38.tmp in the Root folder. This will not affect anything in-game. If you want the terminal to appear again, you can delete d3dx9_38.tmp.

Discord Rich Presence​

Shows your character info & what you're doing in-game on your Discord profile. Obviously, if you don't use Discord or simply aren't interested then this particular mod can be skipped

Installation:​

Manual Download the Main File - Discord Rich Presence and extract the contents of the archive to the game's Root folder.

Combat Lag Fix (NVSE)​

Improves framerate in combat by fixing an engine bug.

Installation:​

Main File - Fast Weapon Lag Fix

Console Paste Support​

Adds clipboard paste support, as well as ctrl left/right and backspace/delete to aid typing in console.

Installation:​

Main File - Console Paste

Improved Console (NVSE)​

Overcomes several limitations present in the vanilla console.

Installation:​

Main File - Improved Console

JIP LN NVSE​

An extension of NVSE adding 1000+ new functions, numerous engine bug fixes/tweaks, and restoring several broken game features.

Installation:​

Main File - JIP LN NVSE

JohnnyGuitar NVSE​

xNVSE extender that adds new script functions, features and engine bug fixes.

Installation:​

Main File - JohnnyGuitar NVSE

kNVSE Animation Plugin​

Allows for custom animations to be loaded without overwriting, making it possible to use animations made specifically for certain weapons without affecting the others.

Installation:​

Main File - kNVSE

lStewieAl's Tweaks​

Plugin with engine bugfixes, optional tweaks and new features with no performance impact. Fully customisable via in-game pause menu (Settings/Tweaks) and with INIs. Changes made in the in-game menu require a game restart to take effect.

There's a tweak for that

It cannot be overstated just how many different things this mod does & how many mods it replaces/obsoletes. Always check Settings/Tweaks in the pause menu before installing additional mods, as Tweaks likely already does it.

Installation:​

Mod Limit Fix​

Greatly increases the plugin limit by fixing a vanilla bug. Improves performance, even if you are nowhere near the limit.

Installation:​

Main File - MLF

New Vegas Tick Fix​

Allows New Vegas to run above 60fps without physics issues, while reducing stuttering and increasing performance. NVTF's memory patches disable Alt-Tab functionality. Follow the Perfomance Guide for the solution.

Installation:​

    • After installation, double-click NVTF and go to INI Files tab. Paste in:
    NVTF.ini

    bAlternateGTCFix = 1
    ; This removes the GTC limits. It should only be used if your game is running at the wrong speeds.
    ; You will need to cap your framrate manually with this enabled.
    bRemoveGTCLimits = 0
    [ThreadingTweaks]
    ; Improves overall performance.

Testing Utilities​

Launch the game using the Tale of Two Wastelands option in MO2 (NOT the NVSE option), and hit the ~ key (above the tab key) to open the console.

Enter GetNVSEVersion, and the console should print NVSE version: 6.

  • If not, xNVSE is installed incorrectly.

Next, enter GetIsLAA, and the console should print GetIsLAA >> 2.

  • If it prints >> 0, then the 4GB Patch was applied incorrectly.
  • If it prints an error message, then JIP LN NVSE is installed incorrectly.

Next, enter IsDLLLoaded d3dx9_38, and the console should print IsDLLLoaded "d3dx9_38.dll" >> 1.

Next, enter IsDLLLoaded mlf, and the console should print IsDLLLoaded "mlf.dll" >> 1.

Finally, enter IsDLLLoaded NVTF, and the console should print IsDLLLoaded "nvtf.dll" >> 1.

  • If not, then NVTF is installed incorrectly.
Before Moving On...

Make sure you passed all of these tests before continuing onto the next section! If any of these tools aren't working correctly, your game will not be stable.
