Good news; new GeForce drivers are available for you to try out. They are almost always very stable as betas go and we rarely, if ever, hesitate to use them. Bad news; the main reason to get them is for those playing Tom Clancy’s Splinter Cell Blacklist or using Windows 8.1 Preview. That said, there are some other new things in the driver release.

This Game Ready driver offers the best gaming experience for Splinter Cell: Blacklist and is also a recommended driver update for the Windows 8.1 Preview. GeForce R326 drivers also provide performance increases for a variety of different games.
