There's a new NVIDIA GeForce driver out on the loose. This is Forceware 182.67 WHQL. The driver is available for Windows Vista 32- and 64-bit and for Windows XP a 64-bit flavor is available.
Very little is known about this driver. Should your graphics card not be supported, included in the archive is a zip file with modified .inf files you can use to make it compatible (courtesy of laptopvideo2go).
These drivers are to be considered beta and thus treated as such. You install them at your own risk, don't complain to us or NVIDIA if they do not work out for you. We have a discussion thread open on these drivers right here.
