I have just installed the Nvidia driver update for OS9 on my D800 with the GF2 card and I must say it works wonders. In IE in OS9 the scrolling even on incomplete pages is spot on. Aliens vs. Predator is even smoother then before at 1280x1024 32bit.
I really want OSX to catch up to this kind of performance in 10.2. I use OmniWeb in X which kicksass all over IE in X but the scrolling is no where near a quick and smooth.
If you have a Nvidia card go get!
