A recurring round, step or increment of logic, behavior and other calculations for a simulation. It is often shortened to update or used synonymously with tick or frame. A simulation update generally has an elapsed time that can be constant or varied. This is often referred to as delta time, which may or may not coincide with the actual passage of time. For example, a simulation update can be faster, the same as, or slower than real time.
A simulation update often tends to be in 1:1 step with rendering a frame — this is the default for Verse. However, a simulation update may be less or more frequent than a frame, such as when an online game client goes out of sync with the server or the physics systems while doing several iterations of the changes of a simulated object. It is also possible that a simulation would not be visually rendered at all.
