For me, W11 seems to have really messed things up with the scheduler. If I'm playing just about any game on my primary monitor, I can't leave a media player window or a browser window with youtube on the second monitor because Windows starves the (visible!) unfocused window if the focused one is using lots of resources. This makes the YouTube video I want to watch in the background stutter like crazy and often completely freeze until I refocus the window. With games that support a gamepad and accept input while not focused, I've started leaving a browser window focused so that it gets correctly scheduled with essentially no noticable impact on the game.
