It won't be long before Nvidia releases its next set of WHQL-certified drivers for its GeForce family of graphics cards, but if you simply can't wait, or want to get a sneak peek at what lies ahead, beta drivers are now available for download.
The beta 258.69 drivers usher in support for Nvidia's 3D Vision Surround technology, "which works with SLI and PhysX controls to combine multiple displays to act as one larger display, allowing a panoramic view of full-screen games or your desktop." Think of it as Nvidia's take on Eyefinity, though it's not exactly the same thing.
Other changes include:
Added support for GeForcet GTX 400M series of notebook GPUs
Updates PhysX System Software to v9.10.0223
Updates the HD audio driver to version 188.8.131.52
There are some limitations in the beta release. Surround gaming with 3-way SLI doesn't work, and the Graph tab on the Adjust Desktop Color Settings page in the Nvidia Control Panel Display Category isn't available.
