Can anyone tell me why Fallout 3 GOTY edition keeps freezing after playing a certain time? Already updated the video card driver. Windows updated. Using Windows XP. Display card is ATI HDI48XX series. Already in windowed mode, no vertical sync, chose medium graphic details.

Thanks.

Do you have a multi core machine with more than 2 cores? –  Frank Mar 23 '11 at 11:30

There seems to be a problem with multi core processors and a suggested fix can be found here. Although it states to be for Win7 I heard it work for other windows versions as well.

Not sure if it's gonna solve your problem, but you might want to give it a try as it's simple to test out (and to reverse the changes if it's not helping).

I found out that is not the fallout_default.ini in the fallout 3 installation folder, it is talking about something like C:\Documents and Settings\user\My Documents\My Games\Fallout3, and there is a fallout.ini, change that, it really work, thanks! –  lamwaiman1988 Mar 25 '11 at 15:43
    
Yep. Worked for me too. Also there is a very good unofficial bugfix patch available. Since applying both of those, I not crashed except when a cat walked on my keyboard and somehow launched Games For Windows Live which has such a horrible interface I couldn't escape it and had to shut down. –  Dronz Jun 12 at 3:14

For non-Steam versions of the game, make sure you have it patched to the latest version, which you can get here

If that doesn't work, I highly recommend this Tweak guide it helped me when I couldn't get it to work on 8.1 but it will work for other OS's. The biggest problem the game has is the multi core one but it might also help to open the .ini file and enable the hard drive cache.

Also (believe it or not) the sound in the game can crash it try to double the sound cache if your system can handle it.

Welcome to Arqade! This looks like a pretty decent answer to this question, but the question is 3 years old with an accepted answer. There is nothing wrong about answering a question this old, but it is much less likely to be noticed. –  ken.ganong Jan 14 at 21:24
    
@ken.ganong - We don't have a problem with bumping old questions with new content, in fact we prefer that questions/answers get updated and added rather than new questions asked. Tristian's answer covers non-steam versions of Fallout 3 (Steam's version is kept up to date automatically). The only thing Tristan - if you could summarise the information in the tweakguides here that'd be great. We prefer to do this in case the link ever goes bad, that way your answer will still be useful :) –  Robotnik Jan 15 at 5:26
