Change your Chromebook’s performance setting

Your Chromebook may use a feature called Hyper-Threading, that is designed to increase performance, like when you are using apps and games. To see if this feature impacts your Chromebook and learn more about the security risks, go to our Chromium page

Note: Google has turned off Hyper-Threading by default to protect our users since it may be a security risk. As a result, some users may notice slower performance with some apps and games.
