Looks fine here on an M1Max MBP. 11 seconds to the login prompt from shutdown.Yeah no. lol
M3 Max here. Sequoia takes much longer to boot from shutdown. If you try to use double click to "Fill", double click, it maximizes the window, then you have to actually drag the window instead of double clicking again (which is a NATURAL to do... Apple again) and the frame drops are out of this world when the window resizes to the original size.
Overall performance is exactly the same as in Sonoma. Aka, it doesn't feel like 120hz feels on a Windows machine. There's jittery / frame drops on animations at random times or events.
Also the "Fill" is a new addition. I don't really see the point but maybe it works for some people.
Fill was not the default on a fresh install and the old option to toggle between zoomed and unzoomed still works fine.
No frame drops or animation issues resizing, moving or activating the window tiling stuff.
Maybe it's a problem with your machine.
