Works fine here on Mac. Might be a Windows-only graphics issue....
seems to be fast for me using Mozilla/5.0 (Windows NT 6.1; rv:2.0b8pre) Gecko/20101121 Firefox/4.0b8pre SeaMonkey/2.1b2pre and a NVIDIA GeForce 310M
Works great on W7 with ATI 3870 card (latest nightly)
On WinXP, comparing http://hg.mozilla.org/mozilla-central/rev/4b9ba5049e66 with Google Chrome 9.0.583.0, the Interaction/Movement on GC is smooth, on Fx it's choppy. Worth to note that the Choppyness with Fx does not come from limited CPU Power, since it's below 100% like on GC all the Time.

The demo is smooth on Nightly on Windows 7, with and without hardware acceleration.
