--- Comment #4 from Timothy Arceri t_arceri@yahoo.com.au --- I suspect it could be your system showing its age. It seems common that users on Windows also reported FPS drops with Danger Zone. You could try some of the generic (non windows) suggestions found here [1] to reduce CPU use etc. Otherwise it might be upgrade time.
