    Re: Howto: Install and use projectM music visualizer with pulseaudio support on Hard

    Just did some googling and found some bug reports that may be effecting me:

    Re: Howto: Install and use projectM music visualizer with pulseaudio support on Hard

    What about other opengl apps? Do they run ok? If they do, I highly doubt any changes to xorg.conf are going to resolve this.

    If it is still running slow even 8x8 texture size that's a serious problem somewhere that playing around with the settings panel in projectm won't fix. You could try pulling down the mesh size to something ridiculously small and see if it's a cpu bottleneck? What is cpu usage like?

    Re: Howto: Install and use projectM music visualizer with pulseaudio support on Hard

    Playing with xorg.conf did nothing

    I reduced the mesh sizes to 1x1 and the texture size to 2 and it still guzzles 100% CPU to give my a low framerate. Reducing the window to within 100x100 ups the framerate to acceptable levels but that is hardly usable.

    Glxgears gives me very good framerates over 800 fps so there shouldn't be any problems with OpenGL.

    There must be something breaking at compile time. Either that or the projectM code isn't optimised for speed for on-board cards yet. Does projectM use more complex mathematics than Milkdrop?

    When it starts up it says "MAX SAMPLES:2048" can I change this setting to something lower?

    Re: Howto: Install and use projectM music visualizer with pulseaudio support on Hard

    Hi all! I'm trying to install projectM like you do it in this tutorial but i get this error:
    Code:
    CMake Error: Cannot find source file "/usr/src/projectm/projectM-Trunk/src/projectM-engine/UserTexture.cpp" for target "projectM"
    Any suggestions? Thanks

    Edit: Actually I use Debian 64bit, but I don't think this is the problem.

    I had the same issue. To fix it, go here...
    https://projectm.svn.sf.net/svnroot/...ojectM-engine/
    Right-click on "UserTexture.cpp" and click "Save Link As..." and save it in your projectM-engine folder.
    Do the same with UserTexture.hpp
    You should be able to generate the makefile.
    Get Busy Livin' or Get Busy Dyin'.

    Could someone help me with this, please?

    No idea what is going on here at all. You should probably log on to #projectm and let the devs know about this problem, sounds like a serious bug somewhere.
