DPI issue?

[Brentar]

So as of late I've been playing the crap outta Battlefield 5. And while sniping I've noticed that when I'm trying to make a microadjustment to my aim by ever so slightly moving my mouse to get that far away headshot, that my cross hair will skip a millimeter or two and ONLY be able to make that small of a distance, so it will stop me from making the adjustment that I need, and thus getting me killed or making me miss my opportunity for a headshot. I usually play on medium sensitivity and high DPI setting. What causes this? is there a way to smooth out the mouse aiming so it doesn't do those millimeter gaps? Its REALLY hard to get pinpoint accuracy no matter what I do unless I crank my in game sensitivity and lower my DPI

What mouse? have you tried cleaning the sensor? cleaning or changing mouse surfaces/pads?
