There's a new NVIDIA GeForce driver out on the loose. 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 graphics cards.
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.
Have you read our GeForce GTX 295 single PCB review already?
