    Too bad Nvidia doesn't play to support the protocol... yet.
    GLX direct rendering does not go through the X11 server.

    More than gaming performance, I would like to know what's with cuda/opencl performance vs other nvidia & ati gfx cards.

    That's interesting and I'm sure you're right about that but you're missing 1 key point - xorg is relatively a mess of code at this point, which is (AFAIK) the reason why wayland was created in the first place. The extra clutter in X makes it more difficult to code for compared to wayland, at least that's the impression I've been getting. For something as complex as GPUs (which IMO are arguably the most complex hardware), anything that can make development more difficult and hindered will probably result in a less-than-perfect result. Since Windows probably gets more attention, doesn't have variations of DEs, and is likely a lot more consistent than X, its no surprise why it generally performs better.

    Yea, it makes sense to compare stock Win7 to stock Ubuntu. Although it would be very interesting to see how it compares to optimised Win7 and optimised Ubuntu (TWM and such ).

    Maybe in 2019 Phoronix will ceases to compare the slow(est) [1] WM [2] to Windows and OSX.

    Who cares of the window manager when the game is fullscreen?
    PTS should support benchmarking in a separate X server, totally blank and without even a window manager.
    I'm looking forward for year 2019...

    * Granted Mint is based on Ubuntu, but A. AFAIR it doesn't use Unity by default and B. Ubunutu is partially based on Debian so I'm not sure it's relevant.

    Ubuntu themselves claim 20M users (was that the right number?), while other distros don't give numbers generally. Even though they don't give out the method, it's pretty much the only number available.

    Somehow I don't put much trust in distro supplied numbers, unless its actual paying customers (E.g. OpenSUSE / RedHat)

    No one here's deciding what is Linux and what is not. This was a comparson between Windows 7 and Ubuntu 12.04 not Windows 7 and Linux.

    There's nothing realible in Distrowatch. None. If you want something that gives even some hint of what popular and what is not then Google Trends is a good start:

    I guess it is fun to test the difference between various Ubuntu spins but this test is not about that. You do understand that it takes time to do tests and those distributions have only a fraction of Ubuntu's userbase.

    What exactly would those results tell us? I mean I think it's a bit more valuable information to know how actually useful platforms perfom than something that is tweaked for just one setup or used by no one.
