Got a problem in your Fallout game? Post it right here, in this thread.
First post is a problem which I solved. I can't tell you all how ecstatic this makes me.
FALLOUT 3 CRASH TO DESKTOP WHOA #1
So this is a bit of troubleshooting for those who might also have this same problem. It's about a very specific CTD I I kept having: crashes at Megaton's gate. Urgh. Maybe the solution below will also take care of all the random CTDs I keep having... usually they'll occur anywhere form a half-hour or later into playtime.
Go into the main Fallout 3 folder and right-click on FalloutLauncher. Maybe you'll need to left-click and
then right-click. There should be a large panel which pops up. Select Properties, and then the Compatibility tab.
Select "Run This Compatibility Mode For" and then choose whichever operating system in the scroll-bar. I've got Windows 8. Click Apply, Click OK.
That is all.
I've walked my character in and out of Megaton like seven times now.
