Basically windows has this mouse acceleration that is on by default?
So I just realized I've been playing cs all my life with mouse acceleration without knowing it. I don't have it on in game but apparently it's on by default on windows.
So mens, have you turned it off manually in windows settings or have you been using mouse accel as well?
If you have 'Raw input' on in cs, the game bypasses the windows settings and gets the input data straight from the mouse. Thsu, if you've been playing with raw input on, you have nothing to worry about.
