@DarthValtrex i think it's down to our connections, i feel i have the same problem too, i main Bloodhound and sometimes when i hear people fighting in a building i like to rush in with my ultimate, just yesterday i rush in, a caustic is looting infront of the door standing still, 3 wingman shots right smack in his throat, nothing not hit marker no sound no nothing , so it is different from hit reg i think because when hitreg was an issue i heard the noise of my bullets connecting (the ting sound) and the x mark on me hitting them but no dmg numbers, now i know for a fact my internet is horrible i get 100 ping but i know there are tons of errors being corrected on my side i check them on my router so i think that if i turn off interleaving i will get packet loss, so due to the router correcting this error some of the info is not being delivered to the server thus when i am hitting a shot on my pc it does not translate to actually hitting the shot on the server, plus sometimes the game hitches and i find myself downed when i empty a full r-301 magazine into someone and it feels like i did over 200dmg but when i spectate i can see they have 70-80 hp left and the encounter goes as follows , i see first i engage full magazine game hitch for a millisecond i die from apparently a single bullet and some sounds do not play like the devotion i die while hearing nothing but then i hear the devotion winding down or the sound of shooting all fighting sounds just do not load.
this is my take on it
