I'm running Windows 8.1 and usually am able to get most games to "behave" but GK3 keeps freezing when trying to go to different area. Freezes to the point where I have to sign out or force restart to get the game to stop. I made sure my graphics card is set to default and tried a lot of different settings in advanced options but still nothing. Please Help!

I've been having the same problem!

try changeding to software render under graphics driver and disable other options.
