walking straight and steady
*jerks a tad to the right to adjust direction
walking straight and steady
*jerks upward to clearly see horizon
walking straight and steady

*cross hair flies all the forget around the screen in a messy "strafing" and spray spam. jerk right an inch jerk left an inch jerk right an inch jerk up an inch.
the only way i can brown townogy this, is like how a squirrel eats a nut it found.
how its jerking its head around in different directions to view his surroundings lol
such unsmooth movements, contrary to realism as well. how can people not get headaches from that?
and its got to be far worse on a tv's stuffty quality to.
