What happens is that all of the characters are replaced by these white orbs or bubbles assuming what I would say would be each in game character's space or coding "zone" if thats the right terminology. It is still possible to talk to characters but all I am looking at is the white bubble itself.
Also cutscenes are cut short as the subtitle alluding to a scene in the Cantena will appear on screen but I just find myself looking at an white bubble infested Hyperion room. Much of the environment itself is intact as I am able to click on the Star Map and select Tosh's mission or the very first mission of the game on Mar Sara (Not sure why that is there.)
Any help would be appreciated and I am relatively sure its a driver issue so I am updating again. Extra feedback would be appreciated and I could probably get some screenshots if it would help on your guy's end.
