Match the fov type across all games if you can, if not try to match with a 0% monitor match, some games like battlefield and modern warfare already do this with certain settings enabled, with 0% monitor match your muscle memory is retained, because 0% mm goes off focal length "angle percent" of fov instead of cm/360 it matches flicks and tracking, but all of this only matters when fov is reduced or increased, otherwise just use cm/360.
