ADS Crosshair deceleration

[50kmh]

Hi,

I've started playing the campaign and I noticed that the crosshair, when ADS'ing, decelerates slowly. In games like CSGO and Battlefield 4, the crosshairs on for example the AWP/SSG and RDS/Kobra sight do not have these issues but the ones in this game make me miss my shots often. This deceleration is very noticeable on scopes that zoom in quite fairly, like the one on the Flatline or any sniper rifle. I have both vsync and mouse acceleration off and I get ~80fps. Any help?

Thanks in advance :]
