I happen to know a little about animation (graphics is a personal hobby 
of mine).  The gold standard in animation is 25 frames per second, or 40 
ms in between frames.

However, as a practical matter, much lower frames rates are acceptable. 
  Some cheaper animation, like some of the early so-called 
"japanimation," used as little as 4 or 6 frames per second in parts of 
their work.

I'd start at 250 ms.  1 ms will clearly overwhelm any normal desktop 
system with too much work.  Get 250 ms working, then see if it can be 
improved.

This.

Peter, what I've looked at in your code base is pretty bad.  Most of it 
is really ugly generated code.  Nothing has comments.  There's no test 
harness that I saw.  You need to slow down and write some code by hand, 
try to understand what is really going on.  One good class is better 
than 100 cruddy classes, and it is certainly my impression that the 
latter is what you have.
