Large Address Awareness

When you start modding games that are compiled in 32-bit (yes most games still are...) you can start getting instability and random crashes due to the game trying to use too much memory. There are a number of ways to do this if you search for "Large Address Awareness Patch". Be sure to backup any .exe files prior to applying this patch and you may also have to re-apply when the game is patched. Finally it is possible that if the game is multiplayer that you might get flagged as a possible cheater due to the fact that you are utilizing a modified .exe file.

32-bit Games Not Needing this (applied by the maker):

  • Skyrim

Crash to Desktop/Purple Textures Glitch

Related to the Large Address Awareness patch if you are seeing purple textures or frequent crashes to desktop do the following:

  1. Open Command Prompt as Administrator.
  2. Execute: bcdedit /set increaseuserva 2500
  3. Reboot your computer.

If this doesn't fix it for you then something else is causing the issue. If you wish to remove this fix do the following:

  1. Open Command Prompt as Administrator.
  2. Execute: bcdedit /deletevalue increaseuserva
  3. Reboot your computer.

Fallout 3 Multicore Fix

Fallout 3 has some stability issues with multicore processors reportedly in Windows Vista and Windows 7. It can cause the game to fail on startup as well as freeze ups during gameplay.

This can be potentially resolved by modifying the fallout.ini file located usually in your Documents/My Games/Fallout3 folder.

  • Run a search for "bUseThreadedAI=0" minus the quotes and change the 0 flag to 1.
  • Then, underneath that line, add the following text line san quotes again: "iNumHWThreads=2"

This should help stabilize Fallout 3 if it's run on more modern systems.

Fallout 4 Multi-GPU Support

Explicitly disable it or risk a ton of crashes and blue screens.


Game won't launch

  1. Make sure a language is selected by going into the properties menu for the game within Steam... Twice now this has caught me.

Moving Games from One Drive to Another


As I now run on a much smaller solid state storage drive, it is becoming necessary for me to move some games to other drives when I'm done playing them. Below are some steps I found on the Steam Forums.

  1. Copy Game Directories to Alternative Drive.
    • Original: C:\Program Files (x86)\Steam\SteamApps\common
    • Destination: D:\SteamLibrary\SteamApps\common (Be sure to follow this naming convention.)
  2. In Steam, uninstall the game.
  3. In Steam, re-install the game, choosing the destination directory in which you copied the game. It should just validate your existing directory without actually downloading anything.
  4. Play the game.
