Why can I run Fallout:New Vegas, But not Fallout 3?

Ok, so I try to run fallout:3 but whenever I get past the title screen it just shuts down completely. I have installed it correctly, yet, It still shuts down.

(I can run Fallout New Vegas perfectly.)

If you have windows 7, sometime it can interfere with that. I guess it has problems with 4 cores as well, so you could always google troubleshoot options for stuff like that, but specifically, I can't help you with more details.

I tried all the FalloutFixes/Nexus forums and it wasnt working for me I was getting really frustrated then I found this. Its so simple and it fixed it, completely no strings attached. it made me laugh at all the trouble I went to like what Kevin Lou did with no results. Here: http://www.youtube.com/watch?v=4GN5HbMsMVE
the d3d9.dll file fixed everything and it was really easy. Good luck Fallout 3 is totally worth it so fight for it!!! ;)

I run windows 7 and I have no issue, but I would suggest going to those forums Weste suggested.

Fallout New Vegas is a much newer game, and is therefore built to run on Windows 7. Fallout 3 has issues with it since it was made for a slightly older OS.

Have you tried opening up the fallout.ini file in: My Documents\My Games\Fallout3
got to the line
bUseThreadedAI=0
and change it to
bUseThreadedAI=1
then add another line after it and insert
iNumHWThreads=2
This limits the game to use only 2 cores in a quad core system and prevent the engine bug from causing the game to freeze.

This should work, one of my other friends had the same problem and resolved it using this method.

I tried it.. But it didn't stop it from crashing when I tried to start a new game. Any other suggestions?

Here's a link for the Bethesda forum for people having issues like you are. Hopefully it helps.
