I setup all three of those and it seems much improved. Thanks for that!
On the Reflektor site, the scrolling is plenty smooth while I'm touching the screen, but when I lift my touch... during the "inertia" of the scrolling, the 3D elements start jumping up and down. Its very visible on the 3D shapes on the about page.
Edit: Interesting... with all the suggested changes, my demo is the opposite. Very smooth during inertia, but a little jittery (but still better than before) while touch scrolling.
