Hello all. As of last night I've has this graphical glitch that makes the game unplayable. I've reinstalled the game and my video card's drivers, and nothing's helped. I've made some screenshots of the error, hopefully that helps. I'll be able to post any additional information you need later on.

Are you using video drivers from your computer vendor's site or directly from the video card manufacturer? Also, what is your video card?
