speed is not the real problem - most people have 5Mbs at least.... problem is latency between the servers. Further away you are, higher the latency and unplayable the "servers".
It has to be decent connection in the same or near state.
I played with a friend who lives in the same city as me (it's not a big city) and it was laggy.
Played with a friend in New york and it was flawless when he hosted because his college campus has a really good connection. Kill Zone Shadow fall had no lag at all.
