I have a new Macbook Unibody 2.4GHz and have installed Vista 64-bit on it (after dealing with the work-around for the boot camp drivers). I've also gone to the Nvidia site and downloaded the latest drivers for it. However when I "rate" the machine with the Vista Experience evaluation my Video is only coming out as a 1.0. I'm thinking that there is something that I haven't updated or need to change because the 9400m chip should be far more powerful than that. Any ideas?
