Our own benchmarks at work show about a 7%-8% decrease in performance

From rom a business perspective, Intel's segmented method is better,

I think intel's messy segmented memory model is quite a hack. At least

3D acceleration is only possible with 64/64 kernel/user, or 32/32, if that

The nvidia drivers provide 3D acceleration for both 64 and 32 bit apps on 64
