Fallout New Vegas is the first game that I have purchased all the DLC from the playstation store. The trouble I'm running into is on the last DLC that I'm currently playing, Old World Blues, the frame rate is terrible. it lags and seems like there is no hope of it resuming to normal. Thus I need to restart & that doesn't seem to do it. Now I love this game & woulld like to finish it, but this is by far the worst I've seen lag compared to any other DLCs for New Vegas or Fallout 3. Would it be more beneficial for me to uninstall everything, by the Ultitmate edition, & start over? Or is there a way to make it so this DLC runs smoother. My PS3 is currently update to version 4.21 if that helps. Any feedback would be greatly appreciated.
