Plutonium

So basically in bo2 multiplayer idk what the hell is going on, enemies kill you the frame they appear and in the killcam they have like 2 seconds of me in good view.
ESPECIALLY sweaty snipers idk how they do it but i see them for like a tenth of a second and i instantly die lmao.
And it's not a ping problem most servers i have 50 to 70 ping
