With Vista, M$ changed their driver architecture. Older drivers may work, but not work well, or not at all. If you haven't downloaded specific drivers from nVidia, then that's your problem. If you have, then you're correct in that they didn't get it right.

As for Vista's new security model, you may want to go read some more about that.

It so bad that there is a threated class action lawsuit against nVidia, the WHQL certified drivers for Vista are causing BSOD's, crosshatching, screen tearing and other nasty things. I may just move over to ATI, I hear they have turned there driver issues around.
