    Default Kernel 3.11 + radeon.dpm=1 results in extremely slow performance

    Hi, any help here? I tried the radeon driver once again today (I have dual screen so I still suffer from the loud fan bug and generally use catalyst). However, after I heard that the radeon driver is at par with catalyst I tried it again today. Everything seemed to be slw as molasses, the gnome 3 menu looks like a slideshow being opened, flightgear gives 1 FPS, I kid you not!! (70 FPS on catalyst) and you should have listed to the fan! It sounded like a jet engine, especially when the aircraft is about to take off!! Youtube videos look like they were made in powerpoint.

    Any ideas as to what could be going wrong? I did check with dmesg, and dpm was on. The power level was at 0, but I forced it to "high" (level 2). That didnt help as well.

    What version of mesa are you using? What graphics card do you have?

    Post the output of "glxinfo | grep OpenGL" it might be that it's using software rendering for some reason.

    1 FPS = software rendering

    Which distro are you on? In addition to the 3.11 kernel you need up-to-date Mesa and radeon Xorg driver

    Using Fedora 19. My order of operations were:

    1. Boot kernel 3.11 in runlevel 3
    2. remove catalyst
    3. reinstall mesa
    4. change the boot params in grub2.cfg and add radeon.dpm=1
    5. reboot


    I will reboot and try again

    You were right. I reinstalled everything from scratch again and this time, its 40 FPS. Much better!! Now only if the loud fan is fixed :-)

    So I installed mesa-libGL, x11-xorg-drv-ati, and removed catalyst. Is that all or do I have to install something else? Oh I did add the radeon.dpm=1 at grub commandline.

    Have you set

    VDPAU_DRIVER=r600
    LIBVA_DRIVER_NAME=vdpau

    as environment variable?

    Yes I have, I have this in my bashrc:

    export LIBVA_DRIVER_NAME=vdpau
    export VDPAU_DRIVER=r600

    Flash still fails and youtube videos do not play. Additionally, if I start VLC with this param:

    vlc --ffmpeg-hw -v

    I get this error when a video plays:

    [0x7f5ca4c45a98] avcodec decoder warning: threaded frame decoding is not compatible with ffmpeg-hw, disabled
    [0x7f5ca4c45a98] avcodec decoder warning: threaded slice decoding is not compatible with ffmpeg-hw, disabled


    Edit: I have got youtube to work. I dont know what I did. However, I am not sure if it works correctly. When i right click on the video and click "stats for nerds

    accelerated video rendering, software video decoding.

    Should the decoding AND the rendering be hardware?
