What it does

In the app the switch is called "NVMe Idle Power Off", described there as: Disables NVMe idle power state transitions to prevent latency spikes.

When it helps, and when it hurts

When it helps

Short hitches when a game reads from an NVMe drive after a quiet moment.

When it hurts

This tweak has no fixed list of registry values to print here: it works through a driver's own settings, scheduled tasks or values that differ from PC to PC (per device, per adapter or per installed game). The app reads what your PC has and changes only that.
