Since I have alot of tearing, I try to select some options in the Nvidia config that makes it a little better. v-sync only makes my game stutter, so to decrease the framerate I try to enable as much as possible. My problem is that when I enable 4x antialiasing - there is no problem in the game (I mean still some tearing but no graphical problems) but when I quit the game, my windows desktop is completely garbeled and I have to restart! This does not happen at 2x antialiasing, so I find it very strange! Even if I tab out of the game the screen is garbled, but if I tab back into the game it is fine! I have a geforce 7900gto and use drivers 93.71. Any ideas?
