There is some new WHQL loving from nVidia out today. This is in the form of another round of updated drivers for their GPUs (including the 9400M/ION). The new driver version also features an upgraded PhysX software package.

In terms of what you are getting from the new drivers you get added OpenGL 3.1 support, better power management, a newer version of Cuda (2.3). For Windows 7 and Vista users you can now set performance levels for OpenGL and DirectX.

Of course there are the usual bug fixes, performance tweaks, and some updates to the control panel UI.
