KF3 mouse smoothing

Hello people, how are you?

I bought KF3 two days ago and when i started a match i inmediatly noticed a mouse smoothing that makes the game feels like sh*t, it's really anoying at the point im rejecting buying the game for this more than for the fps lag spikes that killing zeds make.

How i can disable this sh*t festure? I love the mouse feeling from KF1 and KF2, why apply a mouse smoothing in KF3?
