I've just uploaded a new version which now has directX support. The game now defaults to use the new directX code. You can switch back to using opengl in the new video options menu.
What does OpenGl and DirectX do?
Well they render the graphics basically, some graphic cards work better with opengl or directX so if you're not getting atleast 60fps try changing the renderer in the video options.
If the game is running lower than 60fps please let us know on the forums.
Thanks,
