manning,

just press Ctrl + Alt + Delete and you'll have Windows task monitor measuring cpu effort, or simply import the same song into the aforementioned DAWS (Reaper and Samplitude SE10) and you'll find out the difference. In my point of view if PowerTracks next version evolves to a reduction of around 20% less, of processing power that will be very good. Implementing VST3 specification would also be great: plugins would consume power only when active.

Thank you
