I just yesterday tried Wayland under Arch with a 1070 after a long time. Single WQHD monitor though. Although X11 is really performant, Wayland was more smooth regarding KDE desktop effects. Witcher 3 (via Heroic) showed fewer microstutters and I will try some more proton games and other applications over the weekend.

I recently had to downgrade nvidia drivers from 560 to 550 because wakeup from sleep and hibernate would coredump. I read that this is fixed with 560 but only under Wayland. The developers definitely progressed on the nvidia front.

Easy fix if nothing works. Find the specific pipewire-version that causes the webcam bug, compile and install it, possibly render your sound settings partially defunct on the way and hook up a webcam. Thank me later.

Have you looked into the “Activity” settings within system settings already? When you click on the default activity there you should see the option “Automatically shutting down or sleeping”. I’m sure you already tinkered with the energy system-settings.
