I feel your pain - I have to have V-Sync off and cap framerate with G-Sync on to get even close to playable - V-Sync on even with G-Sync or even FastSync results in unplayable input lag and even then there is some mouse acceleration and some symptoms of the sensitivity changing with framerate really not acceptable in 2016 - its made the game pretty much unplayable for me.
Have no idea what the playtesters for PC were doing as aim down sights is incredibly bad with horrid FOV change, horrid sensitivity and pretty ugly results.
