[Vibe]

I am new to cod4 pc, and I have some questions with commands. I know this might sound really stupid but please help.
-How to I change my sensitivity?
-And when I scope in the sensitivity goes to like 10 and moves to quick how do i change that?

I don't think the sensitivity changes when you scope in..you might just have to get used to what it feels like.

And to change sensitivity just open console and type /sensitivity 10 (you don't have to use 10 of course).
