CPU Core Unparking & CPPC: Stop Core Sleep Downclocking in Games

Eliminate thread wake latency by unparking all CPU cores (100% Core Parking Min/Max), calibrating AMD Collaborative Power Performance Control (CPPC), and deploying a low-latency power plan.

Core C-State Sleep Transitions & Thread Wakeup Latency Penalties

When Windows parks CPU cores into deep C-states (C6/C7), waking a sleeping core when a game thread demands execution takes up to 100 microseconds, causing micro-stutters.

Windows default Balanced power plan constantly puts idle cores to sleep to save tiny amounts of electricity. During fast competitive games, sudden action bursts force the CPU to wake parked cores, inducing frametime hitches. We unhide and configure Core Parking Index to 100%, configure CPPC preferred core autonomous frequency scaling, and enforce full boost responsiveness.
