![](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.

It would seem to me that this efficiency thing/idea has to do mainly with saving battery power. That is fine for devices with a battery, but, my gamer tower PC does not have a battery and the system is powerful enough to run everything I want to at the same time. So, simply, why doesn't Windows have the simple setting of "does this device run on a battery: Yes/No?". Why is that so difficult? BTW, the about:config setting in Firefox from a June 5, 2023 post does seem to turn off Firefox using efficiency mode. And, the command line parameter for the launching of the Chrome browser does seem to work as well. I use Opera as my secondary browser and it is using efficiency mode. Curious that I have not seen any posts on this thread referencing Opera. Also, I did not notice this problem until I updated to Windows 23H2 from 21H2 a week or so ago.

that article seems to have been removed from their site, but it can still be found on the WBM: https://web.archive.org/web/20231217031440/https://techdows.com/2023/07/permanently-disable-efficiency-mode-for-chrome-in-task-manager-windows-11.html

It's a Windows 11 issue, happens with me on any browser, Chrome, Firefox etc. It isn't distinguishing a particular browser brand.

I just ran into this for the first time tonight. At first, I tried the instructions for turning it off for the individual app - it didn't start with Chrome, but with my genealogy program! When I'm doing research, it's not unusual for me to have a dozen programs open as well as a couple of dozen browser windows. Before I finished reading the first article, the stupid app grabbed Chrome! I now have both apps in efficiency hell. My biggest problem is that the option to turn the stupid thing off is greyed out everywhere. There is absolutely no place that I have the option to turn it off for anything. I didn't want Win 11, but getting a new laptop, there wasn't really a choice.

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