The Intel® Dynamic Tuning Processor Participant driver is a component that helps manage the dynamic tuning and thermal behavior of Intel processors. It is part of Intel’s Dynamic Tuning Technology (DTT), which adjusts the processor's performance and power usage in real time to optimize the system's overall performance, power efficiency, and thermal output. This is particularly useful in laptops and small form factor systems, where managing power and thermal constraints is important for maintaining system stability and performance.
