Chugging PS3 performance (due to save file size amongst other factors) was one of Skyrim's few crushing flaws, and the recently-released v1.4 patch contains what should hopefully be a permanent solution to the problem. However, Bethesda's Nick Breckon has revealed another choice tip that should help to maximise performance for PS3 players - and fix the issues as fast as possible.
1. To ensure the fastest jump in performance after applying the patch, be sure to first create a new manual save by entering the save menu and choosing “save game.” You should then restart your PlayStation 3 before continuing to play.
2. If you encounter strange behavior while playing immediately following application of the patch, do not be alarmed – this is a temporary effect of Skyrim scripts correcting themselves after the update. Once this process runs its course, be sure to make a new save and restart your PlayStation 3.
So there. Now fix Nightcaller Temple, please. [Bethesda Forums]
