public class FixedStepSimulationSystemGroup : ComponentSystemGroupRemarks
The value of Time.ElapsedTime and Time.DeltaTime will be temporarily overriden
while this group is updating. The systems in this group will update as many times as necessary
at the fixed timestep in order to "catch up" to the actual elapsed time since the previous frame.
The default fixed timestep is 1/60 seconds. This value can be overriden at runtime by modifying
the system group's Timestep property.

public FixedStepSimulationSystemGroup()Properties
MaximumDeltaTime
Set the maximum DeltaTime that will be processed by this group in a single call to Update(). If the actual DeltaTime is larger, the remaining time will be processed during the group's next Update. This helps maintain a minimum frame rate after a large frame time spike, by spreading out the recovery over multiple frames. The value is expressed in seconds. The default value is 1/3rd seconds. Recommended values are 1/10th and 1/3rd seconds. This value can never be lower than the current Timestep value.

Timestep
