In this video, I cover how to play Fallout New Vegas on Windows 11 without crashing, stutter, or poor performance, using a combination of bug fixing and performance mods, and an optimised FalloutCustom.ini file.

Step 1. Bug Fix / Performance Mods.

When it comes to modding Fallout New Vegas, I would strongly recommend using a mod manager such as Vortex Mod Manager.

Yukichigai Unofficial Patch - YUP

https://www.nexusmods.com/newvegas/mo...

The first mod on the list is Yukichigai Unofficial Patch or YUP, a compilation of vital bug and exploit fixes for Fallout New Vegas, and it's DLCs.

This mod has no dependencies, so you can install it directly using Vortex.

Unofficial Patch NVSE Plus

The second mod is the Unofficial Patch NVSE Plus mod that focuses on fixing bugs using the Fallout New Vegas script extender.

This is also the first mod on the list, that has some dependencies, specifically the New Vegas Script Extender, JIP LN NVSE Plugin, and Johnny Guitar NVSE.

So, make sure to install the mod and all dependencies using the recommended installation method, which is usually Vortex.

IStewieAI’s Engine Optimisations

Next, is a collection of three mods created by mod author IStewieAI.

The first one is the Engine Optimisations mod which rewrites various slow functions in the game in order to decrease loading and saving time as well as improve general performance.

This mod has no dependencies, so install as normal using Vortex.

IStewieAI’s Tweaks and Engine Fixes

The second mod of three, is the Tweaks and Engine Fixes mod, which fixes issues with the game engine, and adds in some optional game tweaks and features with no performance hit.

It should be noted that by default, all features are disable, but they can be toggled on or off using the new Tweaks game menu.

This mod does have some dependencies, in particular, the New Vegas Script Extender, JIP LN NVSE Plugin and UIO or the User Interface Organizer.

As before, install the mod and dependencies using the recommended installation method.

Stewie Tweaks Essentials INI

https://www.nexusmods.com/newvegas/mo...

The final IStewieAI mod is a preset INI file that just contains the essential fixes and quality of life settings from the previous mod, which can be installed using Vortex.

NVTF – New Vegas Tick Fix

https://www.nexusmods.com/newvegas/mo...

The New Vegas Tick Fix, or NVTF mod fixes micro stutter that can occur when playing the game and unlocks the frame rate from 60fps without breaking the physics or lip-sync of the NPCs.

This mod only has a hard requirement of the New Vegas Script Extender, and can be installed using Vortex.

NVTF – INI Presets

https://www.nexusmods.com/newvegas/mo...

The second to last mod on the list is a INI preset for the previous mod, and comes in two version, a Viva Default Preset, and a Texture Modding Preset.

The only real difference is that the latter preset is designed to be used with texture mods, but either can be installed using Vortex.

FNV 4GB Patcher

https://www.nexusmods.com/newvegas/mo...

The final mod on the list is the FNV 4GB Patcher, which is a simple patcher that makes the game 4GB aware, and automatically load NVSE.

To install this mod, download and extract the mod archive, then copy the extracted file into the game’s installation path, typically located at.

Steam / Steamapps / Common / Fallout New Vegas

From here, double click on the file to run, and then close the CMD window once the patch has finished.

Step 2. Create An Optimised FalloutCustom.ini File.

To create this file, navigate to

Documents / My Games / FalloutNV

Take a copy of either the Fallout or FalloutPref.ini file, open the copied file, and replace the contents with the following.

[Audio]
bMultiThreadAudio=1
bUseAudioDebugInformation=0
iAudioCacheSize=16384
iMaxSizeForCachedSound=2048

[BackgroundLoad]
bSelectivePurgeUnusedOnFastTravel=1
bBackgroundLoadLipFiles=1

[Controls]
fForegroundMouseAccelBase=0
fForegroundMouseAccelTop=0
fForegroundMouseBase=0
fForegroundMouseMult=0

[Display]
bFull Screen=1
iPresentInterval=1
iTexMipMapSkip=0
bDrawShadows=0
iActorShadowCountInt=0
iActorShadowCountExt=0
fDefaultWorldFOV=75.0000
fDefault1stPersonFOV=55.0000
fPipboy1stPersonFOV=47.0

[General]
bPreemptivelyUnloadCells=1
iNumHWThreads=3

[Grass]
fGrassStartFadeDistance=11200
b30GrassVS=1

[PipBoy]
fLightEffectFadeDuration=400

Once done, save the file as FalloutCustom.ini.

All done, so launch the game as normal and play.
