On average, every few minutes, the game will just freeze/pause for like 15 seconds or so. It doesn't matter if my character is moving or just standing still. Very annoying/frustrating/irritating to play the game like this! Latest version. Tried adding these lines to fallout.ini's "[general]" section with no effect:

bUseThreadedAI=1
iNumHWThreads=2

Oddly, Fallout: New Vegas, Morrowind, and Skyrim (which all use the Gamebyro engine and are developed by Bethesda) don't have this problem...

Am also trying to get rid of the loading screens but doesn't matter what I do to the fallout.ini, falloutprefs.ini, or fallout_default.ini files--nothing seems to make a difference.
