People have experienced problems with Fallout 3 on all platforms and had to deal with the lock ups, crashes and graphical glitches. Like Oblivion, Fallout 3 was launched with the same type of problems.
So Bethesda’s silence on the matter has finally been broken with a comment on the support forums for Fallout 3, and that is that they are currently working on a patch for all three platforms.
I have never had any of these problem with Fallout 3, but Oblivion I had everyone of those problems and that is when I started to have two save points, one auto-save and one of my own and that is what I have done since I started playing Fallout 3 and seeing I was playing it safe this time none of those problems have found me as of yet. So if any of those things are happening to you fear not, help is on the way.
