I prefer the vertical target assist for sniping and other manual aim weapons... I think I have my sensitivity jacked up to 100. I only snipe on specific maps during Tournament so I prefer the higher sensitivity for the other 95% of the time.
I don't understand how Vertical assist helps in sniping (that's my preferred gameplay). Can you please explain it to me? FYI, I have my mouse sensitivity to 50, I think.
