Energy optimizer with three modes: Power Saver, Balanced, and High Performance.
There is a tiny loss in performance in form of latency as CPU clock is jumping up and down. However, for games where CPU runs at full tilt anyway through entire gaming experience, you won't really see any difference. There are some exceptions to the C states that operate even at full loads and can affect top performance, but is in most cases so small it doesn't matter. Keep it in Balanced and you'll be fine.
Power Saver optimizes system operation by maintaining low power states, such as reducing CPU speed, deactivating storage after inactivity, and putting USB devices into sleep or shutting them down when unused. In a desktop environment this approach is less practical. Balanced mode alternates between energy-saving and full performance based on demand. Certain devices may remain active even in lower modes. For CPU/GPU tasks, the OS will adjust clock speeds accordingly—downclocking during idle periods and increasing only when needed for optimal performance. High Performance settings keep all components running at maximum capacity without lowering base speeds. Note that Power Saver affects performance due to cooling adjustments, which may cause noticeable changes in responsiveness.
