That was my hunch. Thank you.
And yes, 2.0 does have a global timer.

From what I understand each Fx instance uses a separate timer
(functions called using Function::periodical or similar). So:
- With an Fx.Elements instance you will have the styles set (and the
page rendered) 50 times a second.
- With 2 Fx instances, you will have styles set (and the page
rendered) 100 times a second.
So, as JS tends to be quite slow, and re-rendering the page is
expensive, I think that once you hit the limit of how many times the
computer can render the page in a second, you can have jerkiness in
the animations, as each step for each element will no longer be
evenly spaced in time. With many Fx instances this limit can quickly
be reached, especially on older hardware.
(I think MooTools 2 will address this issue with a global timer, so
that multiple Fx instances all use the same timer)
