There's a new NVIDIA GeForce driver out on the loose and it's in fact 186.24. The driver is available for Windows Vista and Windows 7 64-bit.
Very little is known about this driver but it does support most GeForce graphcis cards and also entail a new set of 3D Stereo drivers.
These drivers are to be considered very 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.
