I can play on mid/high sensitivity with my diamondback on painkiller and BF1942 and vietnam. it's not that hard, and BTW razer is extremely comfortable, maybe not at first but it grows on you. but 1600dpi is extremely useful in FPS games, it may be just me but the sensitivity makes me play better. but I guess it kind of sucks in the fact that now whenever I playa pc game I need to use my razer, because all the other mice seem so laggy compared to it, and I'll fall flat on my face playing games because im not used to it.
