has rolled out its Geforce 258.69 beta driver, the first set of drivers to include support for 3D Vision Surround on some multi-GPU setups. In case you missed it, 3D Vision Surround is basically Nvidia's 3D Vision but on three displays.
The new driver supports Geforce 6, 7, 8, 9, 100, 200, 300 and, of course, the 400 series cards as well as Nvidia's ION GPUs. In addition to the support for 3D Vision Surround, the new driver aslo brings a couple of fixes, most notably for the 400 series GPUs.
The new beta driver is available for both 32 and 64-bit versions of Windows vista and 7 OS. You can download it here
