![](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.

I found the solution to the problem. It worked for me. First you have to close Chrome. So you have to go to the desktop shortcut for the chrome and right click and go to the properties tab. In there go to the shortcut tab and in the target field after the text, put a space and put this command in: --disable-features=UseEcoQoSForBackgroundProcess Once you've done that, you can restart chrome and it will hopefully be out of efficiency mode.

Yeah I think this is part of the microsofts efficiency feature things that would really need a settings menu where you could disable it overall or select apps to be exluded from the power savings etc.. For the Chrome issue I think it was enough to append to the shortcut target: --disable-features=UseEcoQoSForBackgroundProcess and haven't seen the efficiency thing since for chrome Not sure if this applies to other programs as well, mostly it was bothering me while using chrome with other programs and it kept turning off videos and such when they weren't in active apps since I was just listening to things while casual gaming etc. Hope this helps anyone else facing the issue.

I switched to Brave browser. Brave is as fast as Chrome (same underlying Chromium engine) but Brave browser (thankfully) does NOT leverage that EcoQOS/EfficiencyMode functionality in Windows. The truth is this: To fix this issue it will require one of two things: Windows 11 would need to be updated to change how EfficiencyMode is implemented. But likelihood of that is <<small. Chrome code would need to be modified to give users control over whether or not their browser makes the Windows EcoQOS system calls. A setting that would disable it entirely. This is the direction that should be taken since it is the application that determines if it is going to make those Windows system calls. Windows doesn't control whether or not an app is leveraging EcoQOS it is a choice the app dev makes. Basically, the Chrome fix is better but it is anyone's guess on when that will be done. Just use Brave and be done with it.

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