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
This patch enables 4GB Large Address Aware memory access and multi-core threading support for Fallout New Vegas, providing a more stable game engine. It works with Steam and is designed to be compatible with all mods, replacing nothing. Ideal for players experiencing crashes or performance issues.
