Keep all CPU cores unparked

Processor performance core parking min cores (plugged in): 100%

Before anything is written, the review screen shows this setting's current value on your PC next to the new one.

May reduce wake-up latency on some older CPUs. Windows 10/11 already unparks cores quickly under load.

Higher idle power and temperatures. Often no measurable change - check with the Benchmark page.

Limited evidence means: popular, but gains are rarely measurable. Expected impact is small (1 of 3): how much it can matter when this is actually the bottleneck on your PC, not a promised gain.

Gains from this tweak are rarely measurable on modern Windows, so it is never recommended or applied in bulk. If you try it, measure before and after with the Benchmark and keep it only if it helps.

No. Packs only contain Safe tweaks, and this one is labelled Caution.

Switch the tweak off in Nexus, or open Restore Center and restore this change (or choose Undo last change). Nexus writes back the original value it recorded before applying, not a generic default, then reads it back to confirm.

• Desktop PCs only: marked not applicable on battery-powered PCs.

Anywhere else, Nexus shows it as not applicable instead of pretending it works.
