The application installs the latest recommended drivers for NVIDIA GeForce GPUs (6-series and above), CUDA, PhysX, and 3DVision software, NVIDIA HDMI audio drivers, and related software. With this release, NVIDIA also introduced an automatic driver update feature. To begin with, GeForce 270.51 WHQL introduced performance improvements in a wide range of games, including SLI performance for the games covered.
