    The gpu1 is constant and linear use, and the gpu2 usage is crazy, this happen in all games. the ulps is off. the fps don't have drops or issues. its good.

    this started to happen in driver 13.12 , in the beta 13.11 v9.5 the gpu's usage scale normal.

    sorry for my bad english but someone have an idea what i have to do to fix it ?

    Try using DDU to clean up the driver first?
    As I know, 13.12 is only a WHQL version from v9.5, with some unknown fix.

    Some things to check:

    If your running 13.12 drivers some have said you need this patch,
    http://support.amd.com/en-us/download/chipset?os=Windows 8 - 32

    Are your cards in PCI-E slots "Two" and "Five"? (The top PCI-E 1x is "One")

    Turn off HPET Support in Bios to see if there is a change.

    When trouble shooting I disable all sound in bios and pull any cards you may have installed to see if that makes a difference. *NOTE* Your video cards have hdmi sound that must be disabled in "Control Panel / System / Device Manager / Sound Devices.

    Set Factory Clocks on CPU.

    I also have a 7950 CrossFireX, and it happens to me too. I believe it is caused by my TX650, but I am not sure.

    Sorry dude, sometimes its the obvious. Don't know till we ask.

    Have you swapped the two cards?

    Swapped Power cables between the two?

    What are the temp's like? Both the same?

    I personally take the coolers off and put good thermal grease on the chip and have found thermal material missing on one ram chip.

    Are your cores parking on the CPU? (Google unparking cores)

    Good luck,

    Or I guess it is something wrong with the frame pacing, try disable it.

    Check your PCI-E or crossfire bridge first?
