I have arrived at Dantooine, as soon as I stepped out of my ship, it was very choppy. Now I can not move pass the hanger, it just freezes in super slow motion. I have gone back to a previous save. I have closed the game and started again. I have rebooted. I have downloaded the lastest video drivers. I have a AMD 64 3200 Radon 9800 pro with 512mb 1.5g mem. Any help please?
