I feel the difference is that this a multi-million dollar game of an almost 30 year old franchise with an expectation of millions of copies to be sold. This is 2016. Not some emulator running on some rollback netcode made by some die-hard peeps in their off-time.
Nice!
So what exactly do you think can happen?
How should a game handle a, say, 200ms difference between a US player and an EU player? Input delay? Is that the high road that multimillion dollar budget developers have to walk, when the result is bad?
At the end of the day, every netcode will have its limits. There is no perfect netcode at all. In any real time action-based game. Especially not in fighting games.
You can have the following preferences:
a. No input delay, only server-client interaction, BUT you demand at max a 60-80ms ping (see: Counter-Strike)
b. Input delay, BUT this method falls off in large distances (sometimes even as early as opponents in the SAME continent).
c. Rollback code, scales very well with distance (if proper precautions are taken), but falls off very roughly after a certain ping threshhold is reached.
The only thing SFV's netcode needs is a setting to set the rollback's intensity, so to speak. With bad connections, it is sometimes better to play "underwater" and with input lag than to see regular jittering and rollbacks.
So.
Based on *my* SFV beta experiences, this netcode is a perfect solution for same continent matchmaking, and can be an acceptable solution to stable ISP, different continent games if the latency is not too high between gamers and capcom's servers. It scales MUCH better with distance than any of Capcom's console online netcondes in the previous generation (where hungary-sweden or hungary-spain was already a bit too much for the code), is considerably better than T6/TTT2 (where the netcode is near perfect for local/sub-1000km matches, but scales not so well with distance increases), and is more playable than P4A/BB games were over same continent-large distance games, again in my experience. How is it not an acceptable solution then?
