![](https://learn-attachment.microsoft.com/api/attachments/e8c660f6-34c2-4550-a3a6-0c856ae2def3?platform=QnA Since yesterday (28 March) Google chrome is unusable. Task manager on my windows desktop says that efficiency mode is active for several but not all sub-processes of google chrome and I believe that is the reason for the drop in performance. I am able to disable efficiency mode for each individual sub-process, but *it returns a few minutes later. I cannot permanently disable it.*Simple actions such as changing a tab or moving the window causes it to freeze for several minutes. I have no recent or current updates to install. Everything is up to date.- There are no other demanding processes / apps running on my pc- I have tried altering Chrome's performance and memory settings. Nothing changed.- This problem is the same with Edge and some other applications.- Efficiency mode is greyed out for the entire application. Only certain sub-processes of chrome are in efficiency mode. The only difference between yesterday and today, is that efficiency mode is active non-stop. I do not want efficiency mode running at all for google chrome as it is the main browser I use for work and school.

Are you sure you don't work for Microsoft? Sounds like you are trying to push people to using Edge. ;) If you are a legitimate poster to this question... It is related to Windows EcoQOS system calls being made by Google Chrome. It will require changes in Chrome to allow users to toggle off calls to the EcoQOS system features in Windows. (Microsoft most certainly isn't going to change Windows for Chrome.) In the meanwhile, Chrome users can use Brave browser. Same Chromium engine and all add-ons will continue to work.

I don't believe this a Windows 11 Efficiency mode issue. We are seeing the same problem across our business using Windows 10 in Australia, Singapore and the Middle East. It doesn't seem to have reached our Europe offices yet. So far, the only fix I have found is to ask all our users to use Edge browser. Anyone else seeing the same thing?

To provide some clarity here. Google Chrome has opted to use EcoQoS APIs more info here Introducing EcoQoS - Performance and Diagnostics (microsoft.com) which in turn puts it in Efficiency mode and that shows the status in Task Manager. Windows 11 only puts it in Efficiency mode when developers have opted to use the APIs. If you are seeing performance issues then you need to contact the Google Chrome dev team and ask to investigate the issue. There could be a possibility of them using it incorrectly or they still need to fine-tune their code to work effectively with EcoQoS. Not to sway folks away from Chrome, but there are many Microsoft apps using EcoQoS including Microsoft Edge (which is based on Chromium codebase) without any performance issues. Task Manager is just the messenger (dont shoot it :) )

How to disable efficiency mode in task manager? Windows efficiency mode is making apps like Google Chrome unusable.
