Well Any map that has a certain grass texture(don't know the exact name) the grass is all stretched and looks bad. Heres a screenshot...
I strongly believe it's direct X 7 or something at least not 9 is used because Dubee had that same error too.
Yes, i think dubee and some other testers had that problem, and it was indeed caused by the videocard using dx7 settings. For them forcing the cards to use dx9 (the way Dee told you to do it) fixed the problem.
