    Default Unity 6.8 Doesn't Change Much For Performance

    Phoronix: Unity 6.8 Doesn't Change Much For Performance

    While LLVMpipe may be a different story, when using hardware-accelerated graphics drivers with the recently released Unity 6.8 desktop, the performance doesn't change much. For at least one driver, there's even a new OpenGL performance regression under certain workloads. Here's some test results of Unity 6.6 vs. Unity 6.8 on the Radeon and Nouveau drivers.

    Canonical really needs to get its shit together and fix hardware accelerated Unity (Compiz). A lot is going for Linux right now: Steam, Lightworks, etc., and Ubuntu is the OS that newbies flock to, so when their games run horrendously on it, they're just going to go back to Windows.

    Sure, Unity 6.8 is even slower.

    I may be wrong, but most performance issues come from Compiz, not Unity (in fact it's interactions between the two but, well...).

    Was a new Compiz released with Unity 6.8? If not, no change regarding performance is not that surprising.

    Why can't they just use Mutter?
    Doesn't it perform better?

    The very first version of Unity (when it was the netbook-remix interface) did use Mutter, but performances were so awful that they decided to re-develop the whole thing as a Compiz plugin.
    Also, Compiz is way more flexible and, has they hired its lead developer, they control it. With Mutter, they would have been slowed down by a not always cooperative upstream (Gnome).

    Now they probably expected things to go better than it is currently, including regarding performances...

    Yes, Compiz 0.9.8.4 has been released shortly before Unity 6.8.

    Seriously, Canonical harms the reputation of Linux systems.
    Using those crappy software components like Unity and Compiz per default is plain non-professional.
    It's a pity Valve targets Ubuntu as their primary Linux distribution.

    Right, so this is about graphics performance of applications running within the Unity environment - what about the performance of Unity itself? Does opening the dash, moving/resizing windows, etc. happen noticeably faster?
