If you have the control SW (Catalyst, I guess), make sure that you set "Antialiasing" (and maybe "Anisotropic filtering" - whatever it means ) to application controlled (see attached). [image: ZOoM_Catalyst.jpg] Note however that the control centre will not substitute an updated driver so indeed make sure your driver is updated. On the other hand, this machine at work has been the second one I have had Ati card on and neither have been really perfect with hardware acceleration on (although thank God, I haven't had display problems with them either).
