What i know about sensitivities : if you like smooth aiming, then use the high dpi. But if you hate smooth aiming ( like i do ) then use the low dpi. Every mouse is different, so don't even try to load usapwnjie.tarquin's config. And every hand is different ofc. How does the gaming mouse help ? - for me it just fits to my hand very well, but if you like to play with smooth aim, then you should buy a gaming mouse. Why people plays with low sens in urt ? - as far as i know, this is the only game wich needs a low sens, in urt you can kill with couple of shots, but in other games like in cs you can hit straight in da head. So your aim has to 'lock' on your opponent because you need four shots to the kevlar to kill the opponent. If you have a high sens, your aim spins around the target, wich makes the hitting hard. Also the movement is a big part of this game, so don't get too low sens. And lower sens needs a bigger mousepad.
