Phoronix: KDE Plasma 5.22 Will Support Direct Scan-Out For Full-Screen Games / Apps

While Plasma 5.21 isn't even out for a few more days, there is now a big reason to look forward to KDE's Plasma 5.22 release later in the year: KWin finally supports direct scan-out for full-screen games/apps!..

Without having looked at how they implement it, the fact that they state "full screen" means that they are probably not using overlays at all (Planes in KMS speak). With overlays, you would get direct scan-out at all times, even when you do not do full-screen. But i guess that people still believe that that should all be handled by the 3d engine, which was the shortsighted, resource wasting, dogma of the 2000s.

Hyperbole. Weston (and maybe sway/wlroots as well, not sure offhand) can already use KMS planes for non-fullscreen surfaces, mutter should get there in the near future (it just landed atomic KMS support, which was the major blocker). I expect kwin will get there as well sooner or later. Meanwhile, this is better than nothing (and better than what's possible with Xorg).

You mean KDE plasma does? Actually, it's GNU-slash-linux...

Slightly better perhaps. Unredirecting fullscreen windows has been a thing in X for a long time. You do get some extra copies when doing the transition though, so from that POV wayland can do a bit better. That said, I don't think kwin supports unredirecting fullscreen windows on X because they couldn't get it to work or something, lols. compiz and mutter certainly could do it at some point in time. Dunno what the current situation is since i don't use either these days.
