    Phoronix: Linux GPU Drivers Prepare For Global Thermo-Nuclear War

    Atomic mode-setting and nuclear page-flipping is becoming a reality within the open-source Linux graphics stack...

    Thanks for the blog link. It's a nice read.

      So what will atomic modsetting and nuclear page-flipping mean for end users? Will it perform better, have greater quality (the linked blog seemed to suggest this), or are they just nessessary just to get it Wayland to work properly?

        Yes.
        Atomic modsetting: should have less flicker, and less risk of corruption of visual output.
        Nuclear page-flippinf: less flicker and tearing.

          This shows how messy the design of Linux's graphics stack is. Apparently whoever designed it in the first place had never played a video game in his life, nor read about graphics programming. Even back in the 80s game developers on C64, Amiga, MSX, etc were utilizing v-sync correctly to create perfect frames yet in 2014 Linux is still trying to figure out how to create perfect frames!

            The frames we get through Xorg are good enough, with or without VSync. Be sure to limit FPS to something reasonable.

              Totally disagree.. Ubuntu with compiz is not tear-free experience and if I take into account Xubuntu where there is no compositor, tearing is everywhere...

                Every recent desktop OS has tearing issues, game consoles have them too.

                But nice troll attempt though...

                  Enables graphic meltdown.

                    Not true. On Windows it's usually the user's choice whether to enable or disable v-sync. When you enable v-sync in a Windows game you actually get perfect frames. On Linux, not so much. Depending on your hardware and driver v-sync might work and might not.
                    On consoles, it's usually the developer's choice. If a developer thinks it's worth it to take some tearing in return for extra performance they do that (Uncharted on PS3 for example), but the console and its OS is perfectly capable of supporting perfect frames.
