The switch does it for *some* games when running portably and then enables most things when docked. A lot of that is battery management.

The steamdeck does not really have a concept of dual modes, per your own statements about playing on a bigger screen.

And I completely disagree that AA isn’t needed on smaller screens. You can see aliasing at any screen size.

Again, perhaps it meets your threshold of quality. That does not mean it meets mine nor does it mean that the form factor somehow obviates it. It just means that we have subjectively different preferences.

But again, I disagree that “it’s not needed”. That’s not why games will disable AA in handheld mode
