The netcode is actually much better than on next gen, the problem is that currently not everyone are able to find easily other players online (as happens to me).
I'm matched w/ people with 1 bars that have screenshot lag for 1 minute (Is it their computers?) Actually, It is solid against people that are nearby. I haven't played the netcode on next gen, so I cant compare
I live in Italy and I played very well with Mr.Wah even if there was no evident lag but 1 second delay. Also I meet for the first time a 4 bar player, thing never happened in 3 years that I play DoA5 on Xbox xD
Like I said my problem is that I can't basically find anyone... and I don't know how I have to act for fixing it =(
Netcode on pc is better than on ps4 and xbox one since I have it on both. Like @Kronin said, it's a pain finding people. IIRC, I played Kronin once as well and I'm from NY. The online was really good. The only time the online sucks is when you are playing 1 bar but then again, playing 1 bar ppl sucks across every console. Just waiting for them to release lobbies on pc so I can run sets with everyone :D
