    The 50% “bug” is not a bug because the Nvidia version has the same “bug”. Gainward just made it that way.

    The tool also works on the new 4870X2 :)

    Works great! PLEASE fix so the speed can be lower than 50%!!! would be awesome cuz anything above 35% is too loud for many people…Great tool keep up the good work!

    I’d like to have the speed below 50% too.
    And also, why are 2D and 3D speeds always the same? When I adjust the 3D speed for example from 50% to 80%, the 2D speed will follow.
    That I could adjust different speeds for 2D and 3D is more important than being able to adjust the speed below 50%, though ^^

    Fix so the speed can be lower than 50%. 35% would be nice. Thank you.
