I've been playing this and my mouse is unbelievably laggy. I can play the game fine, but I hate, hate, hate hate,hate how sluggish it is. I set it all the way up to 10 and its nicer, but its still slow for me. Its not a framerate/performance issue, the game runs almost maxed out (I have anti-aliasing off. My stupid computer hates anti-aliasing for some reason :<) at around 60 beautiful frames. Is there an ini config, or hidden console or something that I can crank up the sensitivity? The 360 controller works nicer in this regard, but I bought this on the PC and would prefer using my good ol' mouse and keyboard.
