I went to Dantooine first, after Telos, everything worked good until then. It (Dant) was a big giant ball of laggy spit. I moved around very slowly until I got around the corner, then it was over. I couldn't move at all. I tried very short movements, but as soon I reached a certain point. Viola! Cease to move. I started an older game, and went to Nar Shadda intead and I'm having no 'real' problems. There are a lot of glitches. Anton wasn't in his cell in the polar region, he was outside the door when Kreia was talking to him. Characters not being in place when cut scene discussions are going on is not uncommon. Staticy sound is another problem. Movies are also kinda bright. This might not be a bug, but I don't think Obsedian did near the job with cut movies that Bioware did.
