A method of optimizing a processing time of a simulation engine that executes to create a simulated experience for a user, includes the steps of identifying a number of components that comprise the simulated experience to be rendered for the user in a virtual reality environment; assigns execution of the plurality of components to at least two threads, where the at least two threads execute in parallel on a CPU to create the simulated experience, where the first thread processes a first portion of the components for components that require rapid execution to create a realistic experience within the simulated experience, and reduces a processing load of the first thread by assigning a second portion of the components to execute in a second thread, where the second portion requires less rapid execution than the first portion to create the realistic experience.
