1. A method of varying physics workload by varying classification of a plurality objects within a three-dimensional scene, comprising: classifying each of the plurality of objects within the three-dimensional scene as a respective first one of at least a static object and a dynamic object; performing physics based operations on the objects for a timeframe; analyzing, by operation of one or more computer processors, workload experienced by processing elements during the timeframe; and based on the workload experienced by the processing elements during the timeframe, reclassifying at least one of the objects within the three-dimensional scene as a respective second one of at least the static object and the dynamic object.
