So I've recently gotten somewhat into CS:GO and have realized that my old sensitivity was really not going to cut it in a series as precise as CS. I've been playing on a 4.8" 360 for the past year and a half or so. For those that don't know what in/360 is, it means I move my mouse 4.8" to turn around 360 degrees in-game. In CS, this is outrageously fast. A couple months ago, I boosted my sensitivity up to a 9" 360. Yesterday, I discovered this spreadsheet. It's an aggregate list of 200+ professional CS players and their sensitivities, equipment, DPI etc. According to that spreadsheet, most pros play at 17-22" 360's. That feels like absolute molasses to me, but it is around what's needed to be very accurate at long and medium ranges, which is where a lot of CS fights take place. I'm probably going to jump up to around 15" and play around with that for awhile. TF2 is on a different level. A majority of fights in TF2 take place in close range, due to the emphasis placed on mobility and most weapons' damage falloff characteristics. We also have the soldier, who needs to flick around approximately 120 degrees very quickly to perform a rocket jump. A lot of fights involve players dancing around the other in an attempt to confuse the other player, or at least make himself harder to hit. For these reasons, I feel TF2 necessitates a higher sensitivity. This brings me to my questions. Do you think it's okay to have two different sensitivities for two different games? I have changed my sensitivity so many times in the past few years and I know it really screws up your aim due to muscle memory. What is your in/360 in TF2/CS:GO or any other Source game? You can calculate it here. If you play at a low sensitivity, how do you handle your mouse? At high sensitivities, you almost never have to worry about resetting your mouse and keeping it away from the edges of your mousepad since it will most likely never leave the center, but at low sensitivities, you're constantly having to lift the mouse to reset. Seems like a whole 'nother skill to aiming.
