    On Unigine's Heaven benchmark, whenever I turn on tessellation I see heavy flickering (graphics flickering, not display).
    I'm also not able to turn on tessellation for Deus Ex: HR or Crysis 2.

    Is anyone else having these problems ?
    I use the 12.1 catalyst drivers (but this has been happening on all of them)

    EDIT: It's the HP Pavilion DV6 6070ee if you need to know.

    Never tried it. Someone else might know though.

    Hi,

    I have an HP Pavilion DV6-6001eh with the same HD6770M mobile VGA card.
    I have experienced the same issue with the original HP drivers.
    With the following steps I was able to resolve the issue.
    1: If your unit has a dynamic swithacble VGA system, download the latest BIOS, and try to set it to fixed mode within the BIOS
    2: Reinstall the latest HP AMD VGA driver from the product page
    3: Download the latest Beta Catalyst driver from AMD (12.11 beta, if you have dot net 4, than use that on, I have used it) Beta driver is not checking the HW like the offical one, so there won't be error like "Go to the Notebook manufacturer for updated drivers".
    4: Install the beta driver, it should be finished wihtout error messages (during the install you may expereinece that the internal LCD panel will became darker, do not do anything, because you cannot do anything)
    5: Restart the notebook, if the LCD is still dark switch the VGA to the Power Saving GPU(Intel) one, the brightness will be good again, than switch back to the Hig Performance GPU(AMD) the brightness should be good again, and you should use the darker/lighter function keys again.
    6: Run Unigine Heaven 3, and test it.

    I hope this will help you!

    BR,
    Birs
