I do not recall there being any mouse sensitivity settings in the game, though there may well be. Perhaps someone else will chime in about it.
I do know one thing that will greatly affect the mouse in the game, and that is if you "shell-out" to windows while playing - er, "testing" your set-up... The game is an old WinXP game, using a single core on your computer, and expects exclusive use of all the resources, especially the video and audio streams. If you use the Windows key, or the <Alt><Tab> or <Ctrl><Tab> combinations to leave the game and go out to the Windows desktop to do something else (or if the cat comes along and walks across your keyboard
), then when you go back in, the game seems somewhat confused, and you will notice the mouse being overly sensitive, as well as other "glitches". The use of high Time Compression settings (sometimes as low as a TC > 2048) can also affect things like that at times.
