How to permanently disable Windows 11 "efficiency mode"?

NO. I am experiencing the same problem. It is not the video card that is the problem. The problem is that efficiency mode causes the video card to crash if someone is using the same browser in two windows to search the internet and watch YouTube at the same time. This is because efficiency mode severely limits the amount of RAM, VRAM, and other resources and when our computers reach that limit the YouTube stops playing. And if someone is playing an online game in multiple tabs - say, Farm Town for example helping multiple friends boost factory production times - then the system crashes because of efficiency doing this. It has NOTHING to do with Nvidia or AMD.

Hello Robert Raio,

Thank you for your attention, but your solution is a palliative, by activating the performance mode the processor core works at maximum frequency and we don't want to damage it right!, we need a definitive solution using it in balanced mode and allowing the deactivation of this absurd feature in the manager of tasks, otherwise I will be compromising my equipment and having the hassle of activating and deactivating the power mode several times, think a little with me please...

solve the problem in a definitive and non-paleative way...

Go into your system power settings and change the power mode to best performance. By default it's set to "Balanced" which does enable a bunch of efficient settings. I was having this problem on my new machine in windows 11 also. Turned this off and my computer is back to full performance like it was before in Win 10. Hope this helps bro!

Maybe a BudLight exec got fired and went to work for Microsoft - they don't learn...

I found what appears to be a "hack" somewhere on the internet. It requires starting Chrome form a Desktop Shortcut, not the toolbar or Start menu. The infection seems to be only on browsers, not other applications. To start Chrome, I now use the shortcut (edit under the shortcut's "Properties"):

"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-features=UseEcoQoSForBackgroundProcess

Now there are no processes falling into "efficiency mode" once we disable Microsoft's QoS algorithm.... Where's the emoji for "rollling your eyes"....
