Late last week, Nvidia's GeForce 260 Series beta driver release leaked to the Web, and with the cat now out of the bag, Nvidia has gone and officially offered them up for download.
Still in beta form, the GeForce 260.63 drivers add support for the just released GeForce GTS 450 GPU. For existing GTX 480 and 460 owners, the new drivers supposedly increase performance in a number of titles, including a generous 22 percent boost in Riddick: Assault on Dark Athena (1920x1200, noAA, GTX 460), as well as a bunch of other double-digit performance improvements.
Other features include the addition of Blu-ray 3D support, HD audio enhancements, a bunch of new 3D Vision game profiles, and a whole lot more.
