My settings for the most legit looking thing i've tested.
ESP OFF! Nothing gives you away faster than you not being able to play stupid about seeing boxes through walls and aiming at them.
fov - 4
smooth - 2
bone - 4/5/6
mind you these settings ARE NOT for those of you who want to run around spraying and killing and getting yourself banned.
these are for people who want to still play with skill but just get an aim-assist similar to that of what you get on a console, no spraying, no running headshots, just a simple little boost to the skill you already have.
BONE:
2-low stomach
3-mid stomach
4-diaphragm area
5-chest
6-upper chest
7-left shoulder(as you're facing them, your point of view)
8-right shoulder
9-neck
10-head
didn't bother testing 1 for some reason, probably RIGHT IN THE DICK.
