Lately I've been having a lot of heavy graphics corruption. I updated to Nvidia's latest drivers, but it still seems to be happening. Anyone seen this, or have any ideas?
Try a clean uninstall of the driver first as well, then reinstall the old one that worked for you and see what happen. Easier and faster than reDL the dat file. Although if that doesn't work, you might need to reinstall the game.
Are you having any other graphical issues with other programs or games? If not then I'd suggest what Brianna said.
I don't know. I never play any other games. ^_^ I did try the fresh driver and no dice, so I started running a gw.exe -image last night, right after reading her post.
