Fallout 3/New Vegas Crash Fix/Reduction: Windows 7
I'm a huge Fallout fan, I was looking forward to playing 3 and New Vegas on my Laptop, cause I've put in a lot of hours on my Xbox 360 versions. However, I use Windows 7, I bet a lot of you do.
First time around, trying to play New Vegas, I crashed after about 10 minutes of gameplay, or I would freeze. It really ticked me off, and I gave up after a while. That was till a close friend of mine got Fallout 3 and New Vegas for himself, and also uses Windows 7. Fallout 3 was giving him problems, so I decided to look into it more.
Turns out there is an .ini fix that will help with the crashing for Windows 7 users. It may not fix it entirely, but it does help the crashing occur less often. And this fix also works for New Vegas. It worked for me and my friend.
What you've gotta do is go to Documents > My Games > Fallout3 (or FalloutNV for New Vegas)
Find the .ini file in the folders. There's one called FalloutPrefs and one called Fallout. Open the one named Fallout in note pad. Before you do that, be sure to right click the file, go to Properties, and uncheck Read Only, or else you won't be able to save it.
Now in the .ini file, press Ctrl+F and search for bUseThreadedAI. Once you find it you'll see is says bUseThreadedAI=0. Change that to bUseThreadedAI=1.
Press Ctrl+F again, and find [General]. Create a new line and add, iNumHWThreads=2.
Now save it. Right click the file again, click on Properties and re-check Read Only, so Steam doesn't save over it. And you should be done.
Like I said, it may not fix the crashes entirely. But it does help them occur less often.
If you have any questions or concerns, feel free to ask me. I hope I was able to help. Give thanks to my close friend too, he helped me out when I got a little confused.
