Performance issues while modifying mesh

    I've been porting our game to Windows 8 (Windows Store with Phone 8.1 SDK) and I'm having some performance issues. We have some animations that scale meshes, as well as we have font on game-play screen where elapsed time of the game-play is being displayed.

    Other than mesh modification, those two things have nothing else in common.

    Disabling the animations and the font modification allows the game to run at 45-60 frames. This is pretty strange in itself that it's spiking by so much, because same things are rendered during those spikes, but I'm still investigating what the issue is there.

    When we start changing font (we use font component from ex2d plugin, but I confirmed it being the same with unity's built in TextMesh) the fps drops instantly by around 15 to 20 fps.

    With animations enabled (those are animation imported from 3ds max and maya and being run with legacy unity animation system, with play on awake flag set to true, so no code is controlling them) it's dipping below 10 fps.

    The device I am testing it on is nokia lumia 830. The same scene runs with steady 30 fps or more on ipod 4, so I doubt the device is too slow (with all the animations enabled).

    Is there some known issues with mesh modification on Windows 8.1? Or maybe I'm missing something else? Any help would be greatly appreciated.

    So, just to be sure, you're running Master configuration, right?

    Just double checked. The issue appears to be the same on both release and master.

    You could try using Unity's profiler, or Visual Studio profiler to examine the problem.

    Or submit a bug with small repro project.

    Yeah, I used Unity's profiler to get to the point I am at, but can't really go any further than animation scaling mesh is causing the problem.

    I will make a version of the project that shows the issue and submit a bug report and post it once I'm done.

    Thank you for your quick response Tomas.

    I got time to prepare a version of my project that presents the issue.

    I submited a bug report and attached the project to it. You can find it here:
    [mod edited]

    There's also a description of how to build it and observe the issue.

    Never post full link to bug like this, because others might be able to access sensitive information, it's enough to print Case number, in this case - 678011

    Uh Tomas, that still had a link (I edited it off though) - have to use the break link icon as editing the text will still hyperlink ;)

    Ops, sorry. Wasn't aware of that (didn't see anything that could be harmful in the link).
