Bioware give us some info!

Ostagar is nearly impassable, Denerim is also a problem, these 2 places the game crashes constantly, Ostagar being the worse, for some reason as soon as I come into these places my pc whines like hell, and soon crashes, at one time my character was just standing around and the game crashed, that's really Buggy suspicous, and game after game it's getting really annoying. I know it's not the computer it runs smooth as silk at any other places in the game no matter how many events are being triggered or enemies on the field to tax the game engine. I suffer no lag whatsoever. My Computer is well and above what is needed for the game. I can only think there are some game crahing bugs to squash, if so then let somebody know, I know it takes time to fully streamline a new game but at least give us a little info on what's happening in these areas.
