NVIDIA has released the latest driver for the graphics chipsets.
The latest Forceware 162.18 is for Windows XP and Forceware 162.22 is for Windows Vista (32bit). (Vista 64 bit)
The latest driver improves the compatibility for Lost Planet and has numerous fixes and compatibility fixes for games and application.

I have tested out the driver with my rather old system and there isn’t a significant improvement in 3DMark05 in the GeForce 7600GS.
My rig spec is as follows:
AMD64 Althon 64 3000+ @ 1.9 Ghz, 2GB DDR RAM, GeForce 7600GS.
Below is the 3DMark05 result (run at 1024×768, no AA/AF)

The improvement is a mere 34 points. But that’s only for my rig, the new drivers released these days improve the latest series of graphics card more than the older series.
Test out the new driver and leave your result here.
