this game makes me sick (literally)

Hey Weasel you can download fraps for free http://www.fraps.com/download.php here, this will let you see your frame rate as well as take screenshots and make movies. Also CMBN runs best for me anyway when the screen resolution is set to the Desktop in the game settings, and my monitor is at it's native resolution. Do you use the Vertical Sync option in CMBN options? if not give that a try as well, that setting may alleviate some of your problems right off the bat.
