Specify how often the Particle System should be Updated.
NOTE: Specifying a value of zero (default) will cause the Particle System to be Updated every time the Update() function is called (i.e. as often as possible).
NOTE: If the Update() function is not called often enough to keep up with this specified Update rate, the Update function updates the Particle Systems as often as possible.
