Well, but there is no option like setting default anti-aliasing, anisotropic filtering etc. in vista as I know... I don't use CCC for resolution or gamma changes. It is for this options I want to use CCC, or ATI tray tools but both of them gave errors.

CCC gives MOM.Implementation and CLI.Implementation errors (it is about .NET I think).

ATI Tray Tools wants to install a driver when installing application, but you know about Vista x64's driver policy.. Of course it fails miserably, and it doesn't work either.

Vista x64 comes with .NET v3 but this doesn't help it seems.

BTW, there is no problem with ATI's 7.6 driver.. It works well. Only CCC creates problems.
