I don't know if the PS3 got all the updates that the PC version has gotten. Patch 1.3 made my game go from Pausing and Stuttering that I had to fix with a third party patch to smooth and crash free. Well, I have had one CTD and two hard freezes, but I almost expect those once in a while with all the things that go on in these games. However, for me on the PC, it has been night and day since 1.3.
For me, 1.1 with an SSD was really great. Then 1.2 and 1.3 introduced intermittent freezing of the console, requiring hard restarts. One restart placed the console into an eternal file restore loop, for which the only fix possible was a clean install of the OS.
I haven't played for real since before the holidays. The last time I created a new character, after the new year, the dragon didn't spawn in Helgen, and when I quit through the settings menu, the game froze on the Start screen, requiring a hard restart.
That's why I'm hoping that one or all of the several crash fixes mentioned in the update will address the hard freezing on the PS3.
