It doesn't happen in any other CoD and since I bought this game I'm having this problem.
I'm from Brazil and my PS3 is manually configured with all ports open (Nat Open), I have a 35/3mb connection, my PSN account is BR and the only way to play with BR's are with a friend in the group, It's not fair cuz when I play against North Americans I always have disadvantage (the connection gets worse than already is)
.
Is anyone having this problem? I'm really frustrated =//
sorry for any english error
