Ok, this isn't really mod related, but I thought I'd post here instead of making a whole new thread. I've already had two freezes, and I read that this is because I have a quad core processor. It said to use this fix:
Open up the fallout.ini file in: My Documents\My Games\Fallout3
Find the line:
bUseThreadedAI=0
change it to:
bUseThreadedAI=1
Add another line after it and insert:
iNumHWThreads=2
This will limit the game to 2 cores and prevent the engine bug from causing the game to freeze.
This was written a long time ago with an earlier patch, but I was wondering if this will still work for me, and if it will screw anything up.
