File removal

  2. Go into Data/Video/

Fallout INTRO Vsk.bik

Mods[edit]

Nexus Mod Manager - the best mod manager for Fallout 3, making the process of installing mods much easier.

Unofficial Fallout 3 Patch[edit]

Fixes many of the bugs which official Bethesda patches never solved
If any of the 5 DLCs aren't present, an older bugged version is installed.

Fallout 3 Script Extender (FOSE)[edit]

Disables Games for Windows - LIVE (GFWL) when run.
Used by many Fallout 3 mods to extend the scripting capabilities of Fallout 3's game engine.
Russian and Polish DVD retail copies, Direct2Drive copies, and the unpatched game (1.0.0.12) are all unsupported.

Fallout Stutter Remover[edit]

Requires Fallout 3 Script Extender.
Fixes stuttering.
The section "bHookLightCriticalSections = 1" under <path-to-game>\Data\fose\plugins has been a cause for stutter for some, and it is therefore advised to set it to "0" if you experience such issues.

Tale of Two Wastelands[edit]

Tale of Two Wastelands combines Fallout 3 and Fallout: New Vegas into a single game. It uses the New Vegas engine. It also requires you to have all of the DLC.

Play without Games for Windows - LIVE[edit]

Games for Windows Live can be disabled as an alternative to using a local profile.
Games for Windows - LIVE Disabler
Requires Fallout 3 v1.1 or higher.
Removes login delay, reducing startup time.
  1. Download and run the Games for Windows LIVE Disabler
  2. To retrieve save games, move files from: %USERPROFILE%\Documents\My Games\Fallout3\Saves\<user-id>\ to %USERPROFILE%\Documents\My Games\Fallout3\Saves\
  3. Use the 'Move DLC's' button to get DLC working again. Steam version of Game of the Year Edition owners do not need to move DLC.

Retrieve Missing Saves
  1. Go to %USERPROFILE%\Documents\My Games\Fallout3\Saves
  2. Search in the folders for your latest saves (if you're were not logged in while saving, the saves will be found in the Saves folder. If you were logged in, the saves will be under your Games for Windows LIVE folder)
  3. Copy the files out to either folder (your username if you plan on logging in each time, or the Saves folder if you do not.)

If you restart the game, your saves should be detected.

Issues fixed[edit]

TweakGuides has created a comprehensive guide for fixing issues in this game. It can be found here.

Game crashes randomly[edit]

Multiple Core CPU Fix[7][8]
The most common fix required for this game.
  1. Open %USERPROFILE%\Documents\My Games\Fallout3\FALLOUT.ini with a text editor
  2. Change bUseThreadedAI=0 to bUseThreadedAI=1
  3. Make a new line after it and add iNumHWThreads=2
  4. If the game still crashes, try iNumHWThreads=1
Disable .Net 3.1[citation needed]
  1. Uninstall Fallout 3.
  2. Disable .NET 3.1 under the "Turn windows features on or off" menu.
  3. Reinstall Fallout 3.

Game crashes on start-up[edit]

Make sure you can log in GWFL
Disable Other Monitors[9][citation needed]
If the game is crashing on start-up, disabling any other monitors in use could resolve this.
  1. Right-click on the desktop and select Screen Resolution from the context menu.
  2. In the Screen Resolution Control Panel, click on the drop down list labeled "Multiple Displays" and select "Show desktop only on 1" (or the monitor you wish to run the game on).
  3. Click apply then on the pop-up window click "Keep changes".
Change FalloutPrefs.ini to reference your current GPU
If fallout3.exe does nothing when trying to open it, your FalloutPrefs.ini may be referencing an old GPU.
  1. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winsat
  2. Open the entry named PrimaryAdapterString and copy the text, it should be something similar to AMD Radeon R9 200 Series for AMD cards
  3. Edit %USERPROFILE%\Documents\My Games\Fallout3\falloutprefs.ini and change sD3DDevice to your PrimaryAdapterString
  4. It should look something like this sD3DDevice="AMD Radeon R9 200 Series"

Crash when starting new game or loading save[edit]

Intel IGPs only: use graphics bypass[10]
Reset codecs[11]
  1. Check if renaming <path-to-game>\Data\Music or <path-to-game>\Data\Video solves the issue.
  2. If so, fix codecs.
Run as administrator[citation needed]

Game keeps minimizing[edit]

Caused by the cursor being active in the background (and clicking Icons, Links, Buttons etc.)
Disable Visual Themes and Desktop Composition[citation needed]

Certain non-conversation voices, such as museum exhibits and random speech, are too quiet[edit]

Editing the config file[12][citation needed]
  1. Open %USERPROFILE%\Documents\My Games\Fallout3\fallout.ini with a text editor
  2. Edit fFilterdBAttenuation=11.5 to 0

Pip-Boy radio skipping or stuttering[edit]

Commonly caused by an issue with current MP3 codec, the format used exclusively by songs played through Pip-Boy radio.
The music may not be stuttering when the game is minimized, with the song played normally.
Fix for Creative X-Fi soundcards[13][citation needed]
Try the Audio Codec fix for game crashes first, if your Pip-Boy radio still skips (test with the enclave channel) owners of a creative soundcard may find that this helps.
  1. Open %USERPROFILE%\Documents\My Games\Fallout3\fallout.ini with a text editor
  2. Edit iAudioCacheSize=2048 to 4096.
  3. Install the latest ALchemy.
  4. Add Fallout 3 to Creative Alchemy: select Use Registry Path and point it to HKEY_LOCAL_MACHINE\SOFTWARE\Bethesda Softworks\Fallout3\Installed Path. Do not install to subfolder. Settings should be: Buffers=10; Duration=5; Maximum Voice Count=128. Leave direct music enabled.
Disable MP3 decoding in LAV Splitter Configuration[14]
Might work with similar codec packs, for example ffdshow.
  1. Open LAV Splitter Configuration program by finding the shortcut in the Start Menu.
  2. In Input Formats tab, find mp3 codec and uncheck it.

Crash when leaving Rivet City marketplace[edit]

Use fixed Broken Steel patch
  1. Navigate to <path-to-game>\Data
  2. Replace the file Unofficial Fallout 3 Patch - Broken Steel.esp with the one found here
