The mutter build I'm using is a bit old though. It's the snapshot right after Xwayland DDX support was added since the newest version of mutter don't work with the rest of Gnome 3.12.
    this patches only work for intel driver, gallium drivers don't have DRI3 support as far as i know, keith sent a patches some time ago for RFC but i never see them in master, so you need recent intel driver

    Depends on the Present implementation of the DDX.
    Looks like the default with the intel DDX when vblank_mode=0 (no vsync) is to do the same thing than the Present fallback.
    However it has a parameter to switch to a better mode (in my point of view) that would do flips instead of copies. That should increase performance.

    Patches to have DRI3 support for gallium drivers are soon landing in master. They are on the ml and reviewed.

    sweet, it seems will be faster than expected , you aware if the patches will require infrastructure at kernel level(not commited yet) for drivers or gallium patches are enough?

    No, they work as is.

    That doesn't mean their DDX will support them though. (Nouveau DDX support it, but it is disabled for the Amd DDX).
