I had to downgrade to the 2960 drivers to get DVI working at all on my GeForce3 Ti 200. Now I'm running at 1280x1024, 75.0 Hz and can play DVDs with ogle. I get no jaggies - the video looks great! Maybe the later drivers break DVI in different ways for different people? Do the 2960 drivers work for you?
Let's reserve the Fs for companies with no drivers at all. But if they aren't giving Andy overtime pay to help us out here, they do deserve a pretty low grade.
