Ok. After playing through Archonage, the Pitt and Broken Steel, Fallout crashed roughly 5 times per DLC. I was amazed at times how glitchy the DLC could be. What annoys me is that the DLC has taken so long to come out on the PS3, they had so much time to test the DLC and look for glitches, and fix them. But they didnt. It seems to me that Bethesda have just quickly adapted the DLC for the PS3 and chucked it on the store, without making any effort to make it run smoothly at all.
