Windows 11: "Efficiency Mode"

Hello everyone,

I just updated to Windows 11 because support for WIN10 will be discontinued in October. Now my browser (OperaGX) is automatically put into the damn "efficiency mode" which causes videos to lag as soon as I switch to another window (e.g. a game). I have unchecked all processes for efficiency mode several times and shortly afterwards (e.g. when the tab is reloaded due to page changes or something) it is automatically deactivated again.

How the hell can you deactivate this stupid, absolutely unnecessary (for me) mode? The power option is already set to high performance.

Greetings,
Alex

@Alexander1883 You need to ask Microsoft, Windows put all browsers on efficiency mode.

If you're looking in the Windows Task Manager, you'll see that it puts all of Opera's processes in a group and that the efficiency mode icon shows next to the Opera group (because 1 or more of its processes are in efficiency mode). However, if you expand the Opera group to see the individual processes for Opera, you'll see that only some of the processes are in efficiency mode. And, if you enable the "command line" column in the task manager and look at the command for each Opera process that is in efficiency mode, you'll see that those processes aren't for page processes and processes for pages are not in efficiency mode.

So, all should be good and you shouldn't have to worry. Your performance issues likely aren't related to some of Opera's non-page processes being in efficiency mode.

Make sure you don't have any limiters on in the GX Control sidebar panel though. Those can cripple Opera and make it slower. Also, make sure "Use graphics acceleration when available" is enabled at the URL opera://settings/system and Adjust the Angle flag for your GPU if needed.

If you want to disable it for Opera, you can do this:

Right-click on your desktop, goto "New" and choose "Shortcut".

In the New Shortcut dialog, browser to "C:\Users\yourusername\AppData\Local\Programs\Opera GX\opera.exe" and click "Next".

Then, name the shortcut "Opera No Efficiency Mode" and click "Finish".

Then, right-click on the shortcut, goto "Properties", switch to the "Shortcut" tab and add a space and --disable-features=UseEcoQoSForBackgroundProcess to the end of the target field command.

For example:

"C:\Users\yourusername\AppData\Local\Programs\Opera GX\opera.exe" --disable-features=UseEcoQoSForBackgroundProcess

Then, apply and OK out.

Then, when Opera is closed, you can start it with that shortcut.

@Ssouled I recently saw someone on Reddit mention that Chromium removed support for disabling efficiency mode. If that's the case, Opera probably inherited the change.
