Get / Set how often the Particle Systems should be Updated.
NOTE: This sets the UpdatesPerSecond property of each individual Particle System in this Manager to the given value. It will also set a particle system's Updates Per Second when the particle system is re-initialized, and when a new Particle System is added to the Manager in the future.
NOTE: Setting this property only has an effect if the UpdatesPerSecondIsEnabled property is true.
NOTE: A value of zero means update the particle systems every time Update() is called.
NOTE: This will be set to zero if a negative value is specified.
