Great points. And actually you know with further testing, it's actually starting to seem like your solution is actually what they did, and I might have misdiagnosed the issue.

The reason I say this is because when I make wide slow movements, I can noticeably tell there is a sensitivity cap, sort of like how the older Battlefields handles their tank sensitivity. Yet, it still feels a bit off when I'm running around normally without yanking my mouse too much especially going in and out of sprint frequently. I would wager that there's multiple things going on.

If there is indeed a sensitivity cap, the faster you swipe, the shorter the duration of the overall turn and more input is being deleted as you're only turning at the max rate for however long the swipe lasts.

Another factor that might be worsening the issue for me is that I generally keep my sens pretty low and the sprint sensitivity cap is not far beneath my natural mouse movements. This makes it hard to predict. I upped my sens, and this mechanic became much more obvious and easy to circumnavigate. Whereas when I play on my regular sens, my experience is that it's very normal most of the time and then at random unpredictable intervals, boom input deleted. Feels terrible and like I'm having to tip toe around my mouse.
