Re: Guns not hitting anything
You are absolutely, unequivocally not alone!
Apart from the current maps (and thus vehicles) making the game frustrating and not fun for infantry gameplay so frequently, the hit reg is the worst thing about this game for me! It's just so so so bad, not sure how this isn't a bigger issue for people.
Perhaps decent machines and connections are impacted more by the awful hit reg (?) I'm usually playing around 120 or so frames per second, 35-40 ping, ~ 950 Mbps internet connection, etc and the hit registration is ridiculous.
