I didn't quantify it, but I have a subjective feeling that rendering is much slower in digital mode, too. That and the fact that there are problems only when the screen is redrawn would suggest that the card is having some problems synchronizing read and write access to the video memory. If that is true, then the source of the problem would seem to be either with the hardware or with the proprietary and closed-source driver, which is to say only nVidia can fix it.

I think I'll try an ATI and let you guys know how it went. If it works, nVidia has lost a customer.
