has just rolled out its latest Geforce 270.51 Beta drivers that bring decent improvements for the GTX 560 Ti and the GTX 580 card. In addition to the performance boost for those cards, Nvidia has implemented its "Nvidia update" feature as well as some updates for Nvidia 3D Vision, Nvidia Surround and Nvidia CUDA.
The new Geforce 270.51 driver features support for all GPUs since Geforce 6 series including ION GPUs, but the main performance improvements are for the GTX 580 and the GTX 560 Ti including up to 326 and 516 percent boost for Dragon Age 2 on single and SLI GTX 580 systems and various other games. Another interesting feature is the new Nvidia update that keeps your PC up-to-date with the latest Nvidia drivers simply by notifying you whenever the new ones are available.
Some updates, including feature and performance, are made to the 3D Vision as well as Nvidia's Surround. The last but not least is added support for applications using CUDA 4.0 features such as Unified Virtual Addressing (UVA) and GPUDirect v2.0.
