Just hide and use a shotgun.
I use 3 for sensitivity in the Source Engine.
forget man, how can you even turn? I play on 12.
what kinda mouse do you use? it does make a huge difference as well
Your mouse looks mighty uncomfortable, and I wouldn't imagine it's that great at keeping a steady course.
I had to use a dell ball mouse for a while because my g5 decided to die on me. It sucked, to say the least. I'm happy I have a g500 now.
