With the announcement of Fallout 4 I decided to FINALLY play Fallout 3 and Fallout New Vegas. Unfortunately, Fallout 3 crashes randomly every 30-60 minutes, mostly when loading new rooms or areas. Although not game breaking, I can't seem to enjoy the game because I'm always anticipating a system lockup. This lingering sense of frustration keeps me from becoming immersed in the game. I have a very minimal set of mods installed, and those are only texture upgrades. The community patches are installed. So I'm assuming it doesn't play well with Windows 8.
It is more likely that Fallout 3
doesn't play well with your multicore processor. Here's the fix that worked for me when I encountered identical symptoms:
Open up the fallout.ini file in: My Documents\My Games\Fallout3
Find the line:
change it to:
Add another line after it and insert:
This will limit the game to 2 cores and prevent the engine bug from causing the game to freeze.
*If the game still crashes write this iNumHWThreads=1
I went on to play 107 hours
without having another crash. What a shame the screenshots of my completed bobblehead collection and cool power armor didn't survive the last forum migration.
Anyway, I hope the fix works for you as well!
