I am using a Sony VAIO PCV-RS 530G. I put a ATI x850 in it and installed the latest Catalyst Drivers package and it doesn't get recognized even when I use the specific path to the folder it is in during setup. The card is working and it works better than it did before running the Catalyst setup but, my device manager stills shows big yellow question marks for this "unkown" video card.
I know what happens. It uses some default basic driver and stuff looks like crap and moves kinda sluggishly. I tried it already.
