I have a 3.2ghz p4 1gig ram with an ATI 9800 and XP. My problem has been slow-downs mainly, but since applying the "fix" on the art pak and deleting the cache am now just left with horrible graphic corruption which starts in a small way and progresses until the game becomes unplayable. Coloured areas on the map suddenly grow lines and angular artifacts that grow into sheets and pyramids of colour that obscure the whole screen. When I get out and then back in again its OK for a while, then repeats. Any suggestions please?
