The Steamdeck loads games into some kind of nested x11 renderer-in-a-window, I think. If for no other reason than to try to avoid Wayland’s extra input latency? Dunno. Maybe you lost some component it needs to work, if regular Steam also does that.

Regular steam does not do that. At this point on most hardware (minus SOME Nvidia, I think older stuff like 2XXX) you should have less latency in Wayland than x11.

I was under the impression that some of the anti-screen-tearing and other features in Wayland unavoidably set a higher (and, higher-enough to be noticeable in some contexts) floor on latency, though, because of how those features necessarily work. I don't mean drivers.

Variable Refresh Rate in Gnome. No screen tearing, no input latency hit for full screen games. To make this work correctly, I think regardless of OS, you need to cap the refresh rate to something just inside the max for the monitor. A lot of games these days have fps limiters. Let's say your monitor was 144hz. You'd want to cap fps to something like 140hz. That's going to prevent any screen jank or input latency.
