Along with the newly released GeForce GTS 450 GPU, Nvidia was ready to launch a major revision of their graphics driver adding new features and claiming performance improvements. In usual fashion, the new GeForce 260 beta driver supports all GeForce families going back to the ancient 6-series, however many enhancements are only relevant to the newer GTS/GTX 400 series.
Nvidia is giving strong emphasis to 3D Vision and related capabilities of its devices. This beta driver adds support for Blu-ray 3D disc playback if you connect your graphics card to a 3D TV via HDMI and have the necessary software. In addition, several bugs have been addressed for 3D Vision supporting games. Some highlights in the performance optimization department can be seen below, for a more detailed list of enhancements look here.
Nvidia has streamlined the driver installer as well, overhauling the user interface and speeding up the process when using multi-GPU configurations. There's also a new Express installation mode that only takes a click to complete. If you are using a Nvidia board for PhysX, this beta driver will also update the relevant software to version 9.10.0514.
