I'm playing the first Freedom Force game at the moment but the mouse sensitivity seems really high and I find it hard to play the game with it this high.
Is there a way of lowering the mouse sensitivity? Because I don't see anything in the options and also checked if there maybe was a configuration file or something.

Same problem here. Bumping just in case someone might know of a solution besides lowering system mouse sensitivity.

Running the game in compatibility mode (either Windows XP or Windows 98/ME) solved the overly sensitive mouse issue for me.

The only other issue I've encountered is that the game (FF) crashes on exit, but the only solution I've found for this is to either put up with it or run the game in windowed mode. The latter can be done by appending "-w" to the executable target in the game's shortcut.
