I just bought myself COD WaW. If I have 'dual video' checked in the game menu I get severe corruption whenever water is on the map or in big explosion scenes. When unchecked it seems to go away. I still have issues though. As you can see in the screen shot below I have a white dotted line along the edges of rivers/streams that flickers on and off. Is this a known issue with ATI cards?
