Runs `powercfg /setacvalueindex SCHEME_CURRENT SUB_PROCESSOR 8baa4a8a-14c6-4451-8e8b-14bdbd197537 1`, enabling 'Processor performance autonomous mode'. This hands fine-grained frequency control to the CPU's own hardware governor (Intel Speed Shift / HWP, AMD Collaborative Power & Performance Control), which reacts in microseconds versus the OS's millisecond cadence — snappier clock ramps under bursty load. Requires a CPU that supports HWP/CPPC (Skylake+, Zen+). Reboot required. Revert returns control to the OS.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
