The input lag can be minimized but not removed to an extend where it wouldn't be noticeable anymore.
First-person has more input lag occurring than third-person.
Turning graphics setting down reduced the input lag by a small amount. (including custom config settings and graphics driver tweaks)
I have a 144hz display and I am using all wired components, this should minimize non game-originating input lag,
Other games do generally not show this behavior.
