If I recall correctly, RefreshForce was used back in the Windows 2000 days.
There was some sort of bug in windows and/or video drivers where games wouldn't run at higher refresh rates, even if your video hardware and monitor was capable. This utility was used to "force" desired refresh rates for certain resolutions.
I seriously doubt that it's needed anymore.
I think this is the homepage...
