    However, for Fedora 21 the XWayland support with 3D acceleration isn't yet ready and will not come until Fedora 22.
    Damn. I was hoping to switch to Wayland completely with F21. It looks like I'll have to wait until F22 since I do all my gaming on Linux. It's great progress nonetheless.

    Almost all Linux games rely on SDL, and if they're new enough then it's SDL2, which supports Wayland directly -- no need for XWayland. My guess is that you'll be able to game fairly well on Fedora 21. (As long as you're OK with the poor performance of the open source NVIDIA/AMD drivers.)

    And notice that it says only Intel is working, AMD & Nouveau will work some day in the future. Closed source drivers some day.

    AMD open source and Nouveau work well with Gnome on Wayland and XWayland. Why shouldn't they? At least I'm not havig any trouble using Gnome 3.12 with nouveau on Wayland.

    Because the article states so and I had troubles with nouveau.

    Stop spreading fud it clearly states:

    Wayland session working with all free drivers (Currently only Intel working, but we expect to have NVidia and AMD support enabled before F21
    Its not just some day in the future its planned for the 21 release.

    Good to hear that. I already game on the open source radeon driver, so I should be ok.

    But if the game also links against Xlib, will it still work ? (e.g. linked statically against SDL)

    This depends on the version. If it's SDL1, it will try to link directly against Xlib and the game will run through XWayland. If it's SDL2 with a version before Wayland support was merged, it will dynamically open Xlib and go through XWayland. Any later version will dynamically open the wayland libs and run natively.

    Note that there are certain functions in SDL2 that are impossible to support in Wayland (eg. setting/getting global mouse cursor or window position), so even if a game relies 100% on SDL2 (no Xlib), it's still not guaranteed to work perfectly well on Wayland.
