Following the launch of its new Geforce GTX 570 card, Nvidia has also released a new 263.09 WHQL driver for GTX 570 and GTX 580 cards.

The new driver package includes HD Audio driver version 1.1.9.0., PhysX driver version 9.10.0514, support for DirectCompute for Geforce 8-series and later GPUs, support for OpenCL 1.0 and OpenGL 4.1, and support for GPU overclocking and temperature monitoring via Nvidia System Tools software.

The release notes file doesn't include any details regarding the performance improvements for the new driver so we'll guess that these are the same as with the previous 260-series releases.
