The new Forceware 87.15 release is available now from Nvidia, fixing 5308's rather annoying once-a-second pausing problem on GeForce cards (like my 6600GT)...

It's a ZIP file at the moment, so just extract to wherever, and update the driver for the Display Adapter through Device Manager.

This is my first blog post from Windows Vista on my main machine at home; with the juddering display updates fixed, I'm looking forward to giving the Febuary CTP a good workout...
