Solstheim runs fine, VERY playable. But when I return to Skyrim, it lags to hell and sometimes even freezes. A temporary solution was to save IN Skyrim and reset the PS3, but it only worked a few times, now it lags less when I load a save in Skyrim, only froze once near Falkreath. Any help? I can't afford to redownload DragonBorn,(limited bandwidth), only the update and game installation.

Please, Skyrim ran smooth until I got back from Solstheim.
