Strange things u do Before/while/after playing games
before: i put my throttle on left side or armchair so it hang down, since i fly helicopters. i callibrate track ir 3-4 times with turning head untill my neck will hurt or track ir will be set as i desire. i put my left hand on throttle, right on joystick, legs on pedals and head for track ir.
while: i rotate my head when i play arma because i use track ir. it's a habbit already so when i play other game i try to look rotating my head aswell.
after: i unplug lots of wires and make sure my neck is still intact
