Question When playing windowed (Fullscreen) games, other apps, including desktop animations, have drastic performance drops ?

Diablo 4 and World of Warcraft are the two games I've tested using windowed (Fullscreen); all other pure fullscreen games work just fine. When either aforementioned game is minimized or out of focus, the framerate on everything else suffers dramatically. Scrolling, tabbing, un/minimizing other windows such as task manager, etc. Even the minimize animation becomes a slideshow. After a period of time of minimizing the game too frequently (i.e., to use my browser for game info etc), the game's performance begins to deteriorate as well, sometimes even leading to a total freeze.

I want to be clear that this behavior was not present on Windows 10 with the same settings. I've also tried setting a generous frame rate limit for the Background FPS setting with no luck. My wife upgraded to Win11 the same day I did and is using the same graphics driver on an RTX 2060 @ 1080p, same game settings, without issues.

Are your games installed on an SSD or HDD?

Also how much room is left on the c: drive? And on the drives where the games are installed? You have plenty of memory so Windows shouldn't need much of a page file.

How many tabs do you have open in all your browser windows when you play the games? That can take up a LOT of memory sometimes.

And Chrome uses so much memory that it's ridiculous, just go look at the Task Manager and the memory Chrome uses. I use the Brave browser, which uses Chromium (also used by Chrome), I have 7 tabs open in 2 Brave windows, but 22 Brave processes are running.
