"Plugin processing is distributed on all available processors when running on a hyperthread enabled or multicore/multiprocessor PC. This allows plugin processing to be completed in a shorter period of time, and thus results in extra available CPU headroom. The actual CPU usage can be viewed in the Windows Task Manager, which can be accessed by right-clicking on the Windows taskbar. "
