    If you are unable to play Diablo III due to an "Unsupported graphics card error", I do have a work-around. But before you do anything, please understand that your GPU is unsupported for a reason. Usually this is because of the absolutely mediocre performance it will get even at lowest settings. Chances are your performance will be so bad that the game will simply not be playable. That being said, there is really no harm in trying out this work-around. Just understand that this is not a *fix* but rather a *work-around* and your performance will likely be awful no matter what. There is nothing Blizzard can do to *fix* this because there is simply nothing for them to *fix*.

    Inside the folder libraries/documents/diablo III there is a file named "d3prefs.txt". Open it.

    - DisableTrilinearFiltering "1" (from 0 to 1)
    - HardwareClass "1" (from 0 to 1)

    Save the file and close it.
    When you launch the game, you will still get the same “Unsupported graphics card” error that pops up. Press esc and the game will load.
    Also be sure to read the blue post below that:

    ...I will try using this workaround personally.

    Aside from the obvious solution of getting a supported GPU? Have you tried doing a HDD search for the file? I just tried it and the file popped up as expected. Maybe give that a go and see if you can find it. If not, Im not sure. It would then sound like your download/install is missing bits.
