I have a notebook with an Ati mobility Radeon 8500 video card. I have installed counterstrike souce on this notebook.. i didn't work. So i tried driver for other video cards, because there was none for my video card. Then i had found one and it worked... no i had to reinstall windows and i have forgotten which driver i hat installed before.. so i had tried the whole weekend nearly any driver for any video card which the new catalyst driver is for. but none of them worked. Now is my question. Do you know any driver or anything else that i can install to play counterstrike source on my notebook? best regards Stellungsfestiger P.s. i'm german, any mistakes in my english are not intended.
