We conclude this chapter with one last thing to review: the hidden power plan setting. The core parking feature enables you to completely shut down CPU cores to save power. Although this feature should be disabled in Windows 10 and Windows 11 high performance power plans by default, you might want to double-check this power setting to confirm it is disabled.

This way you make sure that CPU cores will not be parked which will prevent delays when Windows is parking and unparking CPU cores. These delays may lead to drop-outs in intensive real-time audio processing.
