Fair dues, was it due to your connection or their servers?
Weird really, at the time of the last Pro I had like a 2/3 meg connection at best and it still played very well online for the majority. I'd have some lag problems at times, some games that could be pretty bad, but overall it was mostly good and that's on one of the worst connections available in the country (crappy orange too and I live in a place where they haven't built a better connection and my area can only get 3 meg at most).
Cheers mate,
I know it wasn't my connection, we get good connections here in the US (if you can afford it). My connection is at 50mbps Down and 8mbps up from Cablevision in Bronx NY.
It lagged like crazy. Went to Jamaica and played lag free on a 5mbps connect, so i know some ppl have different stories in terms of online with PES. But most suffers considerable lag which renders the game useless online.
peace
