I have my sensitivity really really high. It's all the way up in game, and it's pretty high on Windows too. This is because I have a shitty stock mouse, and I have about 10-15 inches of desk space for my mouse, so I have to have it really high. Sometimes still though, I do end up punching my tower because I strafe a little bit too much or I don't turn the right amount. It can get frustrating at times (it's happened a few times in scrims where I haven't been able to turn steep enough, and ended up getting killed).
