Laptop Graphic Drivers on Vista RC2

I've got a Dell Latitude D820 @ work and I was a little disapointed with the Windows Aero performance once I installed Vista RC1 and RC2. According to my Windows Experience Index I was only getting a 2.1 which was the score I was getting for the graphics.

Now these things have GeForce GO 7300 which honestly should be working much better. After i installed RC2, I thought that I would have a look at updating the drivers. Nvidia have released a new set of drivers for Vista RC2, but these wouldn't install saying that my graphic card was not supported (So much for Unified Drivers). After a bit of digging on the web I found  http://www.laptopvideo2go.com which modify (mainly the driver information file) the driver pack and allows the Nvidia drivers to be installed. They also reduce the footprint of the driver pack (removing the file that you don't really need).

These worked a treat and increase my graphic score from 2.1 to 3.6 :). The performance is really noticable.

I have just read this morning on Sam Gentile's Blog, that he had the same problem, but he got around it by using the Update Driver in the Device Manager.
