Unless you've been living under a rock during 2007 so far, you'll doubtless have noticed that on January 30th, Windows Vista was finally released to the general public. Since then, we've been hearing plenty about Microsoft's new Operating System, and one of the hottest talking points has been the state of various companies Windows Vista drivers. Much of that particular focus has been on graphics drivers, and ATI and NVIDIA's efforts on that front - Despite putting plenty of work into their Vista drivers, both firms have come under fire for various bugs and performance issues (although admittedly NVIDIA far more so).

We're now more or less four months down the line from Windows Vista's retail release, so just what standards have the two graphics IHVs managed to reach with regard to driver quality in that timeframe? Over the next few weeks, we'll be finding out in what should be a four-part affair, covering both ATI and NVIDIA's DirectX 9 and 10 graphics boards respectively.
