PerfLatencyHint
PerfLatencyHint specifies the processor performance in response to latency sensitivity hints. Such hints are generated when an event preceding an expected latency-sensitive operation is detected. Examples include mouse button up events (for all mouse buttons), touch gesture start and gesture stop (finger down and finger up), and keyboard enter key down.
When set to 0, the processor performance engine does not take latency sensitivity hints to account when selecting a performance state. Otherwise, the performance is raised system-wide to the specified performance level.
