Haven't noticed anything, but TBH I also haven't looked as I've had no need to question things - the rest of the OS runs fine alongside, with dozens of browser tabs, plus both Amazing AI and Draw Things running (though only one actually generating at once). And with about 50 iterations I'm losing around 1% battery every couple of images so it doesn't seem particularly taxing, whilst running cold.

Edit: It isn't obvious with Amazing AI but it may in fact be doing what Draw Things makes explicit in the options, which is generate at 512x512 and use your choice of upscaler to get to 2048x2048.
