While my experience with the Xbox 360 version of Bethesda's Fallout 3 was rather pleasant, PlayStation 3 owners don't seem to be getting on nearly as well. Complaints of choppy frame rates and graphical glitches are peppered throughout Bethesda's forums for the game, with others complaining about random lock ups and various other issues - textures not loading, significant slowdown etc. Two major bugs have already been addressed by Bethesda in the forums, one concerning the game freezing during the GOAT test earlier in the game, and another dealing with the game pausing whenever a PS3 notification occurs. The first issue can apparently be solved by saving and restarting, while they suggest turning off notifications in the XMB for the second.
We've contacted Bethesda regarding these issues, specifically inquiring as to the possibility of a patch to fix problem with the PS3 version.
