I wouldnt say i've seen hackers, but what i have seen is people with the consoles making absurd shots. 95% of my deaths are from console players.
I am getting alot of 1 hits from the SFAR, bullets hitting me behind walls - once, was fighting near the corner, had to reload, so started to move behind the wall, first shot was in open, second shot was right behind wall, couple more shots about 15 feet behind wall. Guy was actually behind 2 walls down the corridor. ( L shape ) . Guy was on console, dont think it was aimbot as such, because would have 1 shot at the corner.
this aim assist they are using, appears over powered.
match - side A mix of comps and *, side B was mostly *. side B was killing in in K/D ratio
