Answer 2

More investigation:

I turned on Memory Saver for Chrome

https://support.google.com/chrome/answer/12929150?hl=en#zippy=%2Cturn-memory-saver-on-or-off%2Cturn-energy-saver-on-or-off I Restarted Chrome Reproduced same slow Meet meetings in Chrome, and same/ongoing meeting displays fine in Edge

I uninstalled Windows 11 update KB5026375

[Windows button--> Settings --> Windows Update --> Update History .... scroll way way to the bottom... --> Uninstall Updates ]

Restarted Windows 11 computer

Now most recent update is showing as KB5026372 (successfully removed KB5026375)

I re-opened all my 20+ tabs in Chrome

I am now able to open and run Google Meet meetings inside Chrome browser with no dropped frames or truncated audio.

It seems that removing KB5026375 update caused Google Meet meetings in Chrome browser to return to expected fast performance.

I have paused updates for the max selectable 5 weeks and I will look for options how to avoid this kind of time waste in the future.

Answer 3

More investigation:

Meet meetings continue functioning fine today with 36 active tabs, and several showing in 'efficiency mode'. Attached screenshot shows resource utilization during a Google Meet session with 5 active video feeds (1 from my machine with video and audio actively up and down).

This suggests that Efficiency Mode is not at the root cause of unusable Chrome or Meet meetings within Chrome.

This suggests that the removal/reversion of Windows 11 update KB5026375 is what transitioned from unusable to usable Chrome and Google Meet meetings within Chrome.

Answer 4

@Jacoui,

See my post

https://answers.microsoft.com/en-us/windows/forum/all/how-to-disable-efficiency-mode-in-task-manager/153cfb3c-5c66-4804-a966-19bdb40d6dd4?page=3&rtAction=1683741517792

Tl;dr - reverting/removing/uninstalling recent Windows Updates resolved this issue for me, and seems like is not related to Efficiency Mode.

Answer 5

My work environment involves >20 simultaneous open tabs in Google Chrome across multiple screens.

Today everything was functional in morning meetings virtual meetings using Google Meet running in Google Chrome in Windows 11 OS.

I ran a Windows 11 update over lunch; between meetings - to get rid of the 'update ready' prompt in the task bar.

In the first (virtual) meeting after the Windows 11 update, I tried leading a Google Meet meeting and it was unusable with behavior indicative of bandwith problems. Wasted a bunch of time for myself and 12 other people messing with a now unusable Google Meet session due to camera and audio dropping frames and several words out of most sentences.

In Task Manager, resource utilization was: CPU 7%, Memory 32%, Disk 1%

Discovered Efficiency Mode applied to Google Chrome as noted in the original post.

Made several attempts to disable Efficiency Mode to get the Google Meet session to be usable.

Opened Edge browser, logged into meeting, and behavior was fine; no indication of 'bandwidth' type problems.

During the meeting, swapped back to Chrome browser (with meeting in progress) and reproduced unusable behaviors similar to 'bandwidth' problems.

Discovered that (within Task Manager), each instance of Chrome can be set to disable Efficiency Mode. I did this ~20 times to toggle every one of the instances' Efficiency Mode to OFF.

Still during the meeting, I swapped back into Edge browser and observed no 'bandwidth' type problems.

While typing this ticket, I am noticing in Task Manager that several Chrome sessions are now showing that Efficiency Mode is active again; despite my having disabled on all instances.

We are extremely frustrated in the amount of our team's time wasted in the unsolicited roll out of un-requested changes which make our high-performance computers and operating system work worse. The result has the same characteristics of a Dark Pattern on behalf of Microsoft to nudge users away from Chrome. The team's sentiment in response to having their time wasted by Dark Patterns is to explore ways to migrate away from Edge and Windows products.

Please revert the un-needed, not-requested code changes which now seems to make my high-performance computer running Google Chrome unusable for my work environment; or allow me to set the mode for all Chrome sessions using one setting set one time which persists on an ongoing basis for all Chrome sessions opened in the future.
