Hello,Here are below 2 screnees of my problem.My specs are in the signature, no over clock at all.Could this be related to AGp chipset of the motherboard?, and how to fix this.This started to happen after I updated the catalyst driver.I have actualy:Driver 6.14.10.6587 and catalyst 5.13VGA memory clock is default 337.5 and VGA core clok is also default 378.0This prob does not happen right away, but after a while playing aroundThanks very much for your input, it will be very helpfull to me. if I could avoid bying a new card, it would be great for my next PC...USER EDIT:I do not know what happened with the screnees, in the forum the resolution looks absolutely awfull, but in real it was absolutely perfect except for the artifacts of course.Screen resolution is 1280/1024/32 by the way.Cyrille de LattreAsus P4P800/PIV 3 Ghz/2 Giga DDRAMATI 9800 Pro 128 MegWin XP SP2 / FS9.1 PSS Beta testerhttp://forums.avsim.net/user_files/138683.jpghttp://forums.avsim.net/user_files/138684.jpg
