Works fine on my PC as well as my laptop. Use a PS2 controller via a USB adaptor on the PC, and a 3GC Steel Series USB PS2 copycat controller on the Laptop. Both systems running Win8 (not 8.1, but 8.0).

Barring some wonky config settings in the Character, System, or map settings (one of those buttons above the slider changes map options, forget the details), it may be something going on with how your particular controller is getting along with your OS.
