    Phoronix: Linux Gaming Benchmarks With Plasma-Next, KDE Frameworks 5

    Up for your viewing pleasure today were some quick benchmarks done of the next-generation KDE desktop stack compared to the KDE 4.13.0 and Unity 7.2.1 desktops of Ubuntu 14.04 LTS.

    I think I pointed out for another benchmark that suspend fullscreen is ignored for Intel hardware... Back then you complained that the GUI doesn't state so, luckily it does so in KWin 5 now.

      Hey Martin,

      Is there a particular reason for that, still? I see this in the KWin code:

      Code:
          if (GLPlatform::instance()->driver() == Driver_Intel)
              options->setUnredirectFullscreen(false); // bug #252817
      but, bug #252817 is a 2010 report originally for i945 hardware. That's not even the same 3D driver as most modern Intel hardware, so I wonder if it's still necessary? If there's still a crash, or broken GLX behavior, we'd definitely like to fix it...

      Thanks!

        What about an up-to-date comparison of DE/WM regarding memory consumption? I don't really care about the non-existent gaming performance of my old Eeepc 901.

        P.S.:Currently sticking to LXDE, but it does feel pretty dated.

          I don't know whether it's still valid. It was valid in 2010 (most often reported KWin bug ever, we spent about a person day just to mark duplicates), than it was fixed, then it came back in 2013. Better safe than sorry and it's not a really useful option anyway. Granted if enabled we will score better in Phoronix benchmarks, but that's not a development aim for us. Unredirect fullscreen doesn't make any sense except for games and for that we have window specific rules and also an X property to disable the compositor all together which would give way better results anyway. As it's by that an option for experienced users we don't see a lot of need for it or to investigate whether the workaround is still needed - better safe than sorry.

            So, seems to be ubuntu is the best way to play in linux.

              Or that Ubuntu's DE works best on Ubuntu.

                Benchmarks are relative thing, you can not conclude for sure what is smoother or faster out of it, but you can repeat the test for you and see .

                Btw i use openbox, but always test xinit when i want to check driver improvments, there are always more or less overhead when testing using DE .

                  Excatly. This is anything but a representative test of desktop environments. On phoronix you see only Ubuntu benchmarks with invalid conclusions regarding to general performance of specific software suits.
                  People stated again and again they don't want to see so much Ubuntu only stuff but michael doesn't care.

                    I already knew that KDE was slow, kinda disappointed that this isn't faster than KDE4 but they still have a few months before the first release to fix it up. Why isn't GNOME in this comparison? Mutter has always felt like the fastest cross-distro composited environment to me. Unity doesn't port well to Arch or Fedora or any distros I run so I haven't used it in a long time.

                      agreeing with Micheal way to test the final distro-environment "as it is" I hope to see soon this comparison:
                      Ubuntu Unity vs Fedora Gnome vs Chakra KDE vs Mint Cinnamon
                      (so then we could complain after the distro releasers - not Micheal)

                        if someone wants to see how thinks work , he or she should pick a distro that deals with every DE equally and not having one specially treated and just forward the others from debian's repository(there I said it)


                        if the unbiased results are not enough to convince someone, then at least he or she must consider using the most popular one(based on user's installation) which is mint.

                        at least I hope that the misleading titles should change to ubuntu *something* benchmark ...

                        (for me, the closest thing to linux benchmarking, is using arch or gentoo or atleast some 1st level distros that build packages from the source and they are not forking them from someone else)

                          I'm sorry for continuing an off-topic, but it is useful. For example, I watch a lot of movies in mpv (-vo=opengl), which requires disabled compositing to be perfectly smooth. Back when I had an Nvidia card and the option used to work, I could watch mpv when it was full-screen and have compositing ready when it wasn't. Now with an Intel card I know I can set a window rule for mpv to suspend compositing but as I like to have it open most of the time that would be the same as having just suspended compositing altogether. Wouldn't you please reconsider just adding a warning, or maybe a new option to kwinrc? Or is there some option already that would allow me to have that functionality back?

                            actually, gnome has about 10% fps drop compared to metacity or enlightenment. tested this with all games where i could and finally got to conclusion that "metacity --replace &" is my best friend when running games

                              most of all users "Linux needs to conquer", don't have time and tech knowledge to look at "how the things work", but they just want an open OS that works at least as the closed ones do (in terms of features, speed and KISS principles): Linux still needs to accomplish these "quality" results (probably just Mint / Ubuntu / Fedora nears them)

                              moreover distro-trends and complexity show that distros and DEs are more and more chaining themselves (eg. Fedora->Gnome+Wayland; Ubuntu->Unity+MIR; Mint->Cinnamon; KDE juggling between Kubuntu, OpenSuse and Chakra) so benchmarking the "main-line products" have more sense that the derivatives to me

                              (as a long time distrohopper I like and use 1st level distros Arch, Gentoo, etc... but benchmarking them will lead to blaming Micheal to use different settings in compiling Kernel, X, Mesa... no please)
