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

[bug77]

Yeah, the bug says it's for "clients on the GBM backend". Tough.

Nice! Now only adaptive sync is left for Plasma on Wayland to become good for gaming.

So not for X11?... :<

correct me if i'm wrong, but with x11 can you at least disable composition before you launch a game? with wayland i don't think you have that option. i know with xfce i just keep it disabled. i play a lot of games and with amdgpu, i actually don't notice as much screen tearing like i use to when i had nvidia.

Wake me up when Windows 10 will get closer to Linux performance and security. Birdie trolling from another account?

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.

In contrast to Xorg, Wayland compositors can unredirect fullscreen windows which cover only one out of multiple monitors.

Funny thing is that despite all of the criticism Xorg receives, I still have better vsync with it + Mesa than on Windows with proprietary driver. It's nice that Wayland offers advantages, but multi-monitor users are a minority and when you run the game on all displays without tilt, vsync still works as expected (including VRR when all displays support it). So let's not always trample down Xorg when it doesn't deserve it, there are still enough cases remaining where this is justified.

Proton fullscreen hack btw. automatically resumes KWin's compositing when alt + tabbing out of a game and you can use it in wine-tkg as well. Thus I don't miss unredirect too much.

Yeah, but disabling the compositor is more of a hack than a proper solution.
It's like a water heater without a cold option: to get cold water, move the pipe out and don't pass it through the heater instead of just using the cold passthrough directly from the heater.

I do not want to lose animations/eye candy when going back to the desktop.

Nice. That is a great analogy that even I can understand.

Except instead of rerouting pipes, all you have to do is press a few keys

Whatever Windows is doing today KDE did at least a decade ago.
