Upon entering Dantooine for the first time, the game proceeds to lag HORRIBLY. I mean something like 1 frame a minute. If I'm in a menu screen (either my own, or a pazaak screen, etc) the game is fine, but when I'm in the starport the game will lag horribly. My character will often shoot off across the entire "level", usually followed by him stopping and spinning around in one spot before the lag becomes so bad the game seems frozen (it's not, I can still go to the menu).
I'm not getting this bug if I go to another planet (Onderon, for example). Also, in one case I managed to move my character around the back side of the Ebon Hawk in the starport - towards and past the Ithorian pazaak player - and the game was fine, but when I circled around the game lagged again.
This is making the game unplayable (obviously) and I guess I COULD start at another planet (though I'd rather not), and it'd be pointless if I could do three planets only to still have Dantooine lag.
Any ideas on how to fix this? I haven't tried the patch, but it had no update about this problem, and in fact seemed to only fix one problem I had (the swoop race bug) and I've heard it's made a bunch of new ones, so I haven't installed it.
