So how exactly do we get our games to tear themselves apart on Wayland now?

Heyo hi! KDE Plasma Wayland user here.

So now that Xwayland (23.2) supports tearing, I'm wondering how we go about enabling that. I've been trying to get my games to run without vsync since KDE added support for it in their compositor, to no avail. "Reduce latency by allowing screen tearing artifacts in fullscreen windows" is enabled.

The games I've been trying are a mix of native and Wine games, such as:

Quake 1, 2, and 4. (Native ports, none use xwayland. Quake 4 is running with SDL 1.2 compatibility layer.)

Battlefield 4 (Wine)

Final Fantasy 14 (Wine)

Elite Dangerous (Wine)

I'm using exclusive fullscreen where available, but something makes me think they're not truly running in exclusive fullscreen mode in Wayland. I have three 1080p 60hz screens, not sure if that'd even matter.

I even went as far as to set MESA_VK_WSI_PRESENT to "immediate". I also don't have a VRR capable monitor.
RX 6700 XT, Mesa/RADV, the usual.

So how exactly are we supposed to get our games to exhibit tearing? I'd love to start playing with Vsync off

Not sure. From what I've heard, some kernel bits for it are still missing? You'd need to dig more into it.

In KDE itself, the setting for it is in System Settings > Display > Compositor > Reduce latency by allowing screen tearing.

But other than that, most recent gaming displays support adaptive sync. It's a lot better than tearing.
