FOV 95, smoothing 7, vis check on, team ignore on — boring starting point that works in Platinum through most Champion lobbies.
Shotguns: head bone, trigger optional. AR/SMG: chest, slightly higher smoothing. Sniper: aimbot off or 140+ smoothing with high delay.
Target switch delay stops you snapping between two players in a box fight like a metronome.
Save configs per input — controller players need lower FOV than mouse at the same skill band.
