[Bf-committers] Game Engine / Physics issues

[Kester Maddock]

Hi Mal,

They jitter because there is no support for stacking, or sleeping slow moving 
objects in the simulation.  Cranking up the physics tic rate, (or setting it 
to zero ie unlocking it) decreases the size of the jitter, but is not really 
a solution.

A blender user works for a publishing company, and has sent me a book on Game 
Physics which should be arriving soon.
