Fallout3 WinXP/7/8/10 Multicore Threading Fix 4GB LAA

or

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

Mod Information.



Steam Guide Available here

Works with all versions including Steam, GoG, Epic Games and Steam Deck.
This enables support for 4GB LAA (Large Address Aware), Multi-core and Threading. As well as 4GB LAA (Large Address Aware) for FOSE.

This should allow for smoother gameplay, faster loading times, better fps, enhanced quality and eliminates crashes by enabling & adjusting the Gamebryo Engine core and threading functions of the game, as well as adjusting other lines, by updating the Fallout_default.ini.
For ini changes see DOCS tab above.

By updating the games default.ini it allows the game to generate a newer fallout.ini with the included changes.
Once the launcher is run the new ini will be generated containing the updated settings.
This saves the need to worry about altering the fallout.ini or putting a write protect on it in order to save changes.

The 4GB patch included works for both the game exe and the FOSE exe, as well it can be used for multiple other games.
Example, Half Life 2 or related games, Portal, Left 4 Dead, ect..
This will enable 4GB Large Address Aware on the file.

Follow these few steps below to get you on your way.

New Vegas Version Here
------------------------------------------------------------------------------------------------------------------------------------------------------------------------
* Works with Windows 11 also
* To unlock the fps check here.
* If you are already using the Steam Anniversary patch for FOSE use, update the ini's and use the 4gb patch on the FOSE.
See FOSE notes below.
*The newest versions of Fallout3 no longer contains winlive and the live button has been removed from the game. (All but GoG)
This is not a mod change, but part of the recent game update to 1.7.0.4.
As a result I removed the winlive download link from additional installs as it should no longer be needed.
*MOD ORGANIZER USERS:
- MO1 and MO2 does run off it's own fallout.ini file, you must replace that file in addition to the other changes in order for this to work properly with it.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------

*Steam Deck Users
Goto Power and switch to Desktop Mode.
This mode acts just like a PC and let's you make file changes or modifications.
Download this fix and update the 3 files in your game. (I suggest the Regular FOV)
You can find your game folders in Desktop mode and place files in those locations.
This will help fix the games crashing issues on the steam deck.
** If you cannot run patch for game.exe on steam deck, copy over to your PC, patch it, then copy back to game folder. Run game normally after.

*If Re-installing after having installed in the past and uninstalled, then re-installing to play again.
I suggest deleting the old game setting & ini's first.
Goto C:\Users\<>\Documents\My Games\Fallout3 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.

To Install:

Make a folder called "originals" in your game folder and copy/paste the original files there.
(fallout_default.ini, fallout3.exe)

Step 1:
Extract the contents of the download.
Place the Fallout_default.ini and the 4GB patch in your Fallout folder.
Steam: C:\Program Files (x86)\Steam\steamapps\common\Fallout 3 (goty)
GOG: C:\Program Files (x86)\GOG Galaxy\Games\Fallout 3
Epic Games: C:\Program Files\Epic Games\fallout3\Fallout 3 GOTY English

All Versions:
Place the Fallout.ini in C:\Users\<>\Documents\My Games\Fallout3.

Step 2:
Run the 4GB patch and select the Fallout3.exe,
apply to enable 4GB LAA. You should get a patch successful screen.

Run Game Launcher. Set hardware and game settings.

Start normally.
Setup your mouse speed ingame under settings.

Additional Installs:

If you have an Intel Graphics install this Intel Graphics - Use the d3d9.dll only.
Place in the game folder.

Additional Step: RECOMMENDED

(click the win10 start button & click the gear icon)
Go to Windows10 Settings, System, Display, Graphics settings
Click Browse and goto the game folder
Steam: C:\Program Files (x86)\Steam\steamapps\common\Fallout 3 (goty)
GOG: C:\Program Files (x86)\GOG Galaxy\Games\Fallout 3
Epic Games: C:\Program Files\Epic Games\fallout3\Fallout 3 GOTY English
Select the Fallout3.exe

Once selected Fallout3.exe will appear under the "Browse" button.
Select it and click "options", select High performance and save.
This will set the GPU for you.
You can do the same for any other games you have.

Please restart your system.
Run game normally after.

To Uninstall:

Move the fallout3.exe and fallout_default.ini files from Originals folder back to game folder.
Goto \Documents folder and delete the Fallout.ini
Run The Game Launcher and setup your hardware again.

Note:
Any alterations or additional changes should be entered into the default ini so it can then be generated in the fallout.ini.
After making alterations to the default ini, delete the fallout.ini then run the launcher again to generate an updated version.
*Fallout New Vegas Version Found Here

***If you have a German version you probably need the winlive fix, since it's a censored version that never had winlive removed
Winlive fix here
Nexusmods.com
and to uncensor that version use with this
Nexusmods.com

*** AMD users please note. The AMD overlay software used in it's Driver software can cause issues with certain games running.
If FO3 does not run even after making changes, disable or uninstall the overlay software and try your game.
In testing I have found that uninstalling the overlay software usually works best.
------------------------------------------------------------------------------------------------------------------------------------------------------------------------

FOSE Setup
Not required to run the game.

Steam or Epic Version.

Apply the following patch first:
Steam Anniversary Patcher for FOSE use
Update the ini's if you have not done so and use the 4gb patch on the FOSE after.

Normal FOSE setup works fine with GoG version.

Adding the Fallout3 Script Extender
- Download and extract the files to your game folder.
- Steam: C:\Program Files (x86)\Steam\steamapps\common\Fallout 3 (goty)
GOG: C:\Program Files (x86)\GOG Galaxy\Games\Fallout 3
Epic Games: C:\Program Files\Epic Games\fallout3\Fallout 3 GOTY English
- Run the 4gb patch and direct it to the game folder, apply it to the fose_loader.exe.

Make a shortcut to your desktop from the fose_loader.exe and launch from this.
Make sure to have run the game from normal launcher at least once, before running from fose.
Start and play.
Suggestion: Add it as a non-Steam game to your library, to run it through Steam.


Gameplay - This series will show that you can play a crash free and stable game with just this simple fix.

The only 100% PROVEN FIX.
A Main Quest Play-through in God mode to test the games limits and speed up the story-line.
Playlist link
Part 1 Uses the Enhanced FOV, Part 2 and on is Regular FOV

Final Notes* Mod Users.

Although this helps correct the main game and DLC and helps with mods use, it cannot fix "all" mod issues.
It does however let you know that you are building your list on a stable game.
If a mod is broken or causes issues or crashes, you should let the mod author know.
- They may be able to give additional help or suggestions.
Check if you have an overlay issue
- Some overlays can have issues with things like ENB or similar add ins, make sure this is not the issue.
Try restarting your system.
- Fallout can get quirks as a result of file changes or updates and a simple PC/System restart will fix many issues.
Lastly, check to ensure you have no conflicts between mods and that you have installed them properly.

Thanks a lot for this!
Fallout 3 is still my favorite game along with Oblivion. My next run I'll make use of this. I wish there was something like this for Oblivion too. Thank you!

Need help (info on other mods in general) please.
I'm pretty new to mods themselves, FO3 is already installed on my laptop but I haven't started a game, I really I want to play Fallout 3 but I want to put it on steroids for my first playthrough. I want to add mods as long as it doesn't change the core story/world. Example, if I was playing Doom 1 for the first time (let's pretend there's an actual story there too) I'd want to add HD sky, HD graphics, zombie mutator sounds, Metal music mods, and even Brutal Doom or Project Brutality, but I wouldn't want to add mods so that all of a sudden I'm killing enemies or bosses from Duke Nukem, or change the weapons to Duke Nukem weapons(or that of any other particular game), or change the textures to that of Wolfenstien, or change the game play of that into a survival horror.
Instead of going through ALL these wonderful ideas, reading and reading, and weedeing out the ones that aren't stable yet can someone please give me suggestions on mods to use the first playthrough that will give me a Vanilla Fallout 3 on steroids experience?
After reading this mod, I'm def going to be using this one my first run. As I said I REALLY want to play this game already, but if I can get some good suggestions... preferably mods that work well with each other. Any mods where you think back saying "I really would've liked to play with this mod on my first run." Ideas?

This site is the wrong site to ask these questions. For bethesda games always check the Nexus mod site, not only they have more mods, they have them more detailed too.

Hi,
For a vanilla run.
I would use mtui for resizing the game text (looks alot nicer). Then run it with the enb and sweetfx to sharpen the look of the game without altering it. Check the recommended mods, they are all for a vanilla run-through and will help the game without changing it. If you check the mod description, you'll find find it under other useful mods. Those are the ones that you'd want in a vanilla run through along with this one. Sorry it took me awhile to answer. ModDB didn't notify about this one, kinda came across it checking things over. PM me if you need any other help.

Hi, Im trying to run this game on windows 10. I have followed absolutely all the steps in the video but every time I try to tun the game from the shortcut it opens the crashed and tells me it has stopped working immediately. And when i try to run it through steam it does the same. before I did this it did work fine, I didn't have the best fps so I thought this would help, I could play before now I cannot. I have also put it in vista compatibility service pack 2.

EDIT: And yes I did restart my computer after I had done everything.

Sorry I missed this comment, didn't notify by email. What you want to do with Win10 is goto the nexus one here Nexusmods.com? and make sure to install the winlive update, it includes the gfwl in it. As well as the Directx9 Final Release. You extract it to c:\dx, then goto c:\dx and run dxsetup to install it.
Also if you put in the ENB, remove that in case it is what is causing the issue, only place it after the game
is running, as you may need an alternate enb launcher for the enb to work.
Lastly, check your video card type. If it is an intel graphic, download the intel graphics fix and place the d3d9.dll only from that mod into your game folder with the game.exe.
Pm me directly to chat more if you still need help.

Followed steps closely, but everytime I try to play from the fose loader, a message comes up saying the application cannot run on my PC

Have you restarted after applying the patch and updates? In some cases it requires a reboot. Is this win8 perchance?
