XWayland Linux Gaming Performance With GNOME Wayland On Fedora 21

[agd5f]

I posted a patch on the mesa mailing list a few months ago to enable the EGL_KHR_create_context extension in the gallium drivers, but nobody was interested in reviewing it. This also allows the client to create core contexts as the default seems to be to create a 3.0 compatibility context.

SDL 2.0.4 also has a patch that enables the usage of this extension when EGL is used.

Feel free to ping the list again. Sometimes things fall through the cracks.

Thank you. The discussion and his patches are here. While this extension isn't important for desktop environments (they use OpenGL ES 2, AFAIK, so they don't need to specify a minor version number or flags), other applications (e.g. games) could need it. Its absence could delay EGL (and Wayland) adoption, as explained in one of the messages.

This is not the case. The reason for that is that games under wayland run composited (no matter whether there are running native or using xwayland). The performance "overhead" of xwayland is pretty much non existent. On X we do unredirect games so they do run uncompisted means that they run faster.

I do have patches for mutter to do the same on wayland (weston already does this btw.) but they didn't get finished in time for 3.14.

I really hate it to read things like that, I hope they'll implement those patched as a 3.14.x update instead of 3.16.

Are you using the open-source drivers?

Yes, open-source drivers.

This bug may be related. In EGL versions prior to 1.5 (which Mesa does not implement), the EGL_KHR_create_context extension is needed to create contexts with a minor number (or other flags).

xmir is better

xMir performance was much better!

It's called reading guys.... ever heard of it?:

How do manage to get wayland running? Is there any aditional steps to take of packages to install on fedora 21? I just did a clean install but when I select the wayland desktop option in the gnome login I only get a pointer on the upperleft of a black screen and then the login screen comes back. Also steam say
I have the exact same graphic card as was used in the article but wayland won't work and neither will 32bits games (0.AD works fine for example).

OpenGL GLX context is not using direct rendering, which may cause performance problems.

???

Xmir is Broken and also has a compositor bypass unlike Xwayland in Gnome and Xwayland in Gnome is getting a compositor bypass in the next release or as a update

when? for gnome 3.16?
