    Firstly the machine specs

    Mac Pro 2009 4,1
    Mountain Lion 10.8.2
    Quad-Core Intel Xeon 2.66 GHZ
    Memory 6 GB
    XFX Radeon HD6870 card

    Yesterday I swapped out the Radeon HD4870 card for the 6870 and updated the kext file, before I did this I could play GW2 at medium settings with good results now the game lags all the time, IE: When moving through the game world its all speed up slow down not good at all.

    Same machine but running the game under Windows 7 in Bootcamp and it all runs fine with higher settings.

    Sounds like HW acceleration (QE/CI) is not working in OS X, so you have a driver issue.

    Here - http://www.groths.org/?p=431

    But I only used the ATY_Init.kext file and the Kext Helper b7 to install it.

    The ATI Graphics Update.pkg I left well alone.

    Weren't you the guy who initially said he didn't want to mess with non-standard cards, and thus ruled out a modern NVIDIA card? You realize that a Fermi or Kepler generation card would've worked right out of the box, no need for third party hacks or custom drivers? Can't help but think it would've been easier to just get a GTX 680 or something.

    I don't know anything about AMD cards so hopefully someone else can help you figure this out.

    OP, I noticed you had a thread about flashing your 6870. ATY_init should not be used with flashed cards.

    As I recall, one of his requirements was to have boot screens maybe?

    why I did not buy a GTX 680, the cost.

    Hello,

    I have the 6870 in my 2009MP, and it's working very well. I simply plugged it in and booted up. No drivers, no nothing. Try it with the init file removed.

    Probably ATY_init was not installed properly then. Try playing a DVD in DVD player. If it doesn't work, that's your problem.
