Microsoft is testing a new feature in Windows 11 called Low Latency Profile that gives a short boost to your CPU for 1 to 3 seconds when you open apps or menus.
Early tests show Microsoft apps like Edge and Outlook open up to 40% faster, while the Start menu and other menus can load up to 70% faster, with CPU use jumping high for a few seconds then dropping right back down.
Microsoft says this is normal because Apple does it in macOS and Linux, plus phones use the same type of quick CPU boosts for better speed.
The feature is only in early Insider testing now, so it is not out for everyone yet.
