LatencyHintEpp

  • Article

LatencyHintEpp specifies the processor energy performance preference 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. This setting is only applicable to Enabled autonomous performance states systems.

It is also used for Deadline Quality of Service performance. The value could be changed by setting LatencyHintEpp in Media QoS profile.
