Are you running Direct X 8? What operating system are you running? Have you tried reinstalling DX?? IF you are running XP, then you should upgrade to DX9, or install SP2 because it comes with DX9.
ok i just recently downgraded to an x850 xt and install cat 6.2 and now the cmesh problem has dissapeared. i can alt tab now!!!! i dont know what it was the new card or the driver
x800 xl cat 5.5-5.8 -- cmesh problem
x800 xt cat 5.8-5.11-cmesh problem
x1800 xl cat 5.12 - 6.2 - cmesh problem
dont alt tab. i had the same problem until i switched to nvidia. problem solved. not to put down ati.. i switched from an x800xt to a 7800gt and the issue never came back. has to be an ati issue.
alt tab doesnt crash my video game, it just takes a long ass time to get to the cs screen again after it is alt tabbed. Kinda sucks since i end up dying after the re alt tab after someone messages me.
