Praise the heavens! Nvidia has released its first DirectX 10-certified drivers for. It's about bloomin' time too -- geeks the world over have been tearing their combovers out because they couldn't get Nvidia cards to work properly with Vista.
The drivers work with the GeForce 8 series of graphics cards: the 8800 GTX, 8800 GTS 640MB and 8800 GTS 320MB, all of which are monstrously quick. You can download the driver from this link here -- but be warned: at the time of writing only the 64 bit download was available.
