Multiplayer on the ps3 version is horrible...the frame rate is so bad when u have a close encounter with an enemy u never find out what happened...and don't rely on the killcam to explain...the whole killcam system is waaaaaay off...it takes a whole clip to kill somesomeone...then u die with 2 shots...armor or not...the assist system is **** up...this could be a really good game if this was fixed

it takes a whole clip to kill somesomeone...then u die with 2 shots...

That's host advantage dude. Be patient. The next game it could be the other team which can't seem to kill you and you're mowing them down.

you seem to be talking about lag. Personally, my only issues as of yet are framerates dip but not horribly. As for the lag, i havent experienced any.
