Not driver related. same version on both machines, BUT the system that works right is windows 7 home premium 32 bit. The system that it works slow on is windows 8 64 bit. I installed the android app and it flies with that, so there seems to be something slowing it on win 8 and i'm wondering if it's because it's 64 bit? I know media center isn't using it because it has been disabled along with other processes related to it.
