📋 About This Mod

4GB NV-MCTF - Multi-Core Threading Fix, for short

NEW UPDATE, NEW. INI's, BETTER MADE

PLACE AND PLAY

What This Mod Provides

4GB Large Address Aware, NVSE launcher  -  Increase the 2GB to 4GB LAA, reducing crashes

Multi-Core Threading     -  Properly uses modern multi-core processors for better FPS

Three-Group INI System   -  All ini files now aligned so the launcher can't silently undo improvements

4GB NVSE Support  - Script extender users get the full memory benefit

Smoother gameplay, faster load times, better FPS, eliminates crashes

Works with Steam, GOG, Epic Games and Steam Deck  |  Windows XP through Windows 11

A major benefit of MCTF is that it is entirely .ini-based, meaning it is not game version dependent.

Information on the 4GB Patch can be found here, through NTCore

This should allow for smoother gameplay, faster loading times, better fps, enhanced quality and eliminates crashes

*If Re-installing OR applying changes to ini's - After having installed in the past and uninstalled, then re-installing to play again.

I suggest deleting the old game setting & ini's first held in the mygames folder.

Goto C:\Users\<>\Documents\My Games\FalloutNV and delete all the old files, "except" the save folder.

This will allow the game to create new files and ini's for the newest install.

Make a folder called "originals" in your game folder and copy/paste the original file there. (Not Required)

1. Extract the contents of the download.

Place the ini's and 4GB patch in your Fallout folder.

Steam:  C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas

GOG:    C:\Program Files (x86)\GOG Galaxy\Games\Fallout New Vegas

Epic:     C:\Program Files\Epic Games\FalloutNewVegas\Fallout New Vegas English

2. Place 4gb patch in your game folder
