Timer Resolution

The default timer resolution on Windows* is 15.6 ms – a timer interrupt 64 times a second. While in connected standby, the resolution will be changed by the operating system to 30 seconds. When programs increase the timer frequency (decrease the timer resolution), they increase power consumption of the platform.

The Timer Resolution shows the time spent in each resolution interval during the collection period.
