Thank you all for 10000+ Endorsements

FNV4GB is a tool to load Fallout New Vegas with the Large Address Aware executable flag set so the entire 4GB Virtual Memory Address Space can be used by the game. This is useful when using lots of Mods and Texture Packs.

Why use this tool, when there are 4GB patch tools and PE Editors you might ask? Well the Steam envelope for the FalloutNV.exe does not tolerate any tampering and will error out if you modify it that way, so this tool was created by MonochromeWench to get around that limitation.

It is recommended to copy the FNV4GB.exe and fnv4gb_helper.dll to the New Vegas installation directory. Doing so will allow the tool to work with ENB, SweetFX, FXAA injector and other such utilities with a minimum of hassle. However it is not necessary (YMMV).

Create a shortcut to FNV4GB.exe and place it on your desktop, pin it to your task bar, or copy it to your quick launch bar.

First, make sure you have launched the game with the default launcher AT LEAST ONCE after setting up your graphics options or the program will NOT function properly.

Make sure Steam is running. Then run FNV4GB.exe as Administrator to launch the game.

FNV4GB will automatically load and execute NVSE if detected.

If you want to use an ENB, SweetFX, or FXAA Injector you need to add the following launch options to the shortcut
"C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas\FNV4GB.exe" -laaexe .\FalloutNV4GB.exe

If you have the English Polish Czech Russian (ENPLCZRU) version of Fallout New Vegas you need to add -SteamAppId 22490 to the launch options

"C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas\FNV4GB.exe" -SteamAppId 22490

If you want to use xinput1_3.dll to add controller support then you to add the following launch option to the shortcut

"C:\Program Files (x86)\Steam\steamapps\common\Fallout New Vegas\FNV4GB.exe" -extradll xinput1_3.dll

You may combine launch options to allow use of multiple functions.

Please visit the Fear and Loathing in New Vegas STEP page for instructions on how to use FNV4GB with Mod Organizer.

Install New Vegas Stutter Remover

New Vegas Stutter Remover

Make sure the NVSR .ini has bFastExit = 1

This will prevent your game from hanging on exit.

The .ini is located in the Data\NVSE\Plugins folder with the .dll, after you have run the game at least once with it installed.

If you want to use Fake Full Screen then use:

1. Does this work with NVSE?
YES, it detects and launches NVSE automatically.

2. Does this work with ENB?
Yes, it works with both the wrapper and injector version. Wrapper is recommended.

3. Why doesn't this work with my ENB or SweetFX?
You haven't read the documentation for this tool or for ENB or SweetFX.

4. My antivirus says this is a virus/trojan?
It is NOT a virus. Please post in the forum what antivirus you use and EXACTLY what it is being detected as. I can then submit the program for white-listing.

5. Does this tool work with FakeFullscreen?
No, use OneTweak if you need it.

6. This program deleted/ruined my game, blew up my computer, killed my cat, etc.
