Interesting problem (and really the only one i'm having) the Game will freeze for about 5 to 10 seconds and when it recovers, some of the skins would be out of wack. ie, the weapons will change to a solid purple color, or NPCs face will go solid black, or a certain skin let says ED-E's will take the place of all the skins in the game.
The fix is to alt-tab out and back and everything is back to normal.
Anyone else having this problem?
I'm running BFG's GTX275 Video Card.
