Just bought the Fallout 3 GOTY, I have not installed the addons yet, but I want to, but I seem to be getting some problems with the main game, after about 5 to 20 minutes of gameplay, it just stops... I have to hit ctrl-alt-delete to get out, as it would be stuck for ages. Loaded up the task manager and it says that Fallout 3 is not responding.. My system specs are...

Operating System: Windows 7 Home Premium 64-bit (6.1, Build 7600)
System Manufacturer: Acer
System Model: Aspire M3910
Processor: Intel® Core™ i5 CPU 650 @ 3.20GHz (4 CPUs), ~3.2GHz
Memory: 3072MB RAM
Available OS Memory: 3064MB RAM
Page File: 1913MB used, 4210MB available
DirectX Version: DirectX 11
Video Card: NVIDIA GeForce 315

I have it on "Run as Administrator" and got it's compatibility mode on "Windows XP Service Pack 3", however it froze a lot more without the compatibility settings and running it admin worked well... But I only got about 20 mins tops. The game itself runs fine, no lag nothing just that the game stops responding after a while of play time. Any help?

Yiu have to use a proper game-playing video card, not a mere business graphics cheapie of a device.

While your CPU is not a quad-core chip, it is a dual-core one that supports HyperThreading. Try the the Multi-Core Fix?:



Find your .ini file in your My Documents\My Games\Fallout3 folder ...it is the configuration settings file named FALLOUT

Open it with notepad and do a CTRL+F to search for the line

bUseThreadedAI=0

.....change it to =1


and below that line add this line

iNumHWThreads=2

Thank you! Worked, played for about an hour and no stops.
