Hi all
I'v just built a new system with all the newest drivers including the newest cat drivers. I get 12400 marks in 3Dmark03 which I think is fine but when I try and play doom3 I get very poor frame rates even at low settings with no aa af.
I had to uninstall the new cat drivers as they were causing blue screen error like 0X0000050. So took them off and I'm now using an older version.
same performance with both.
My old 9800pro played doom3 at high settings. could this be a dodgy card?
the pci-e power cable is connected
