Efficiency Mode is greyed out(Windows 11)

Im on Windows 11 and i have the problem that some pocesses are in effiency mode. I can't turn this setting off in the task manager because its greyed out. Is there a way to disable the effiency mode when its greyed out or do I have to live with it? (I found this problem because a game was lagging but my cpu or anything else was over 30%)

 

Cannot disable efficiency mode on Firefox.

I cannot disable efficiency mode for firefox.

How do I permanently disable this feature for Firefox? The option to do so is greyed out in the task manager. For other programs, efficiency mode can be enabled and disabled, but not for Firefox, which is also the only program to be in efficiency mode. I do not want my browser to run unnecessarily poorly.

 

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



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.
