For a long time, some people have complained that under Windows 11, the performance of the device can not be fully played, and Microsoft is obviously receiving information, so the change is inevitable.

In the upcoming "Sun Valley 2" feature update, Microsoft will introduce a new feature for Task Manager to pause applications that use too many system resources. This function is called "Efficiency Mode" or "Eco Mode", which can extend the battery life performance of the notebook.

When this mode is enabled, it also improves overall performance by pausing resource usage for processes that are manually selected by the user. This can be achieved by highlighting a specific process in Task Manager and then selecting "Efficiency Mode".

Windows 11's new "efficiency mode" reduces the priority of processes to "low," but it doesn't kill processes.

Microsoft has been testing "Efficiency Mode" for a year, and it has observed up to 4x performance improvements (76% reduction in resource usage) on CPU-intensive systems. This results in better UI responsiveness, which also improves the speed of the task manager itself.

Efficiency mode can benefit all types of applications if used properly.
