In the game folder in Windows you will find a Reset.reg file that will clear the Geocore registry entries. EVERYONE ON EVERY OS MUST REMOVE THE PREFS OR THE GAME WILL NOT FUNCTION CORRECTLY FOR YOU. New installs do not need to worry about it. For other operating systems the preference file locations are as follows:
On Mac OS X PlayerPrefs are stored in ~/Library/Preferences folder, in a file named unity.AnarchyInteractive.Geocore.plist
On Windows, PlayerPrefs are stored in the registry under HKCU\Software\AnarchyInteractive\Geocore
On Linux, PlayerPrefs can be found in ~/.config/unity3d/AnarchyInteractive/Geocore
Also, if you are having FPS issues there are now legacy executables for each OS. You will find them in the game folder alongside the normal executable, they are named with the legacy tag.
