Jaggies!!!

They're everywhere, and this PC is equipped with 2 nVidia 8800s with SLI!!!
You'd think I could get some decent anti-aliasing out of that.
Why is FS9 so stubborn about keeping its jaggies? I've turned every anti-aliasing setting in the control panel to max and it made no impact. Can anyone help me exorsize the jaggies?
(Note I have never worked with nVidia graphics cards before)
