I have this problem in my new laptop after few minutes the game hang but the sound keep playing and I read about it here in the forum also I searched google in hope for finding solution for it and the only solution that I found that I must change and add some lines in the Fallout.ini file; I did that and the problem gone but unfortunately I got bad performance in the game... not the case as before... the game was ruining smoothly without glitches or something like that until it hanged completely....
Here is the solution that I found:
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.
By the way I run most recent games smoothly without any problems like Call Of Duty Modern Warfare 2 so please nobody tell me the problem related to my computer specs (the computer spec written blow)...
My game version: Fallout 3 Game of the Year
My laptop spec:
Windows: Windows 7 64 bit
Processor: Intel Core i5 2.4 GHZ
Graphic Card: ATI Mobility Radeon HD 5145
Memory: 4 GB DDR3
Note: all drivers are up to date....
I hope I find solution without losing any performance....
