I feel the whole port thing is a dumbass idea to begin with for all the games. Consoles can't get new games, so they shutoff backwards compatibility and require "extended features" to try to pull the plug on their older consoles. If only game companies had enough backbone to say "no" to this bullshit.
About 10 frames of delay while offline, the menu selection is laggy, and I think that's about it. It's not the worst thing if you're just a casual or trying to get back into it but for those mlg prohs it's pretty devastating.
Yikes. And they were advertising it as having less input lag than PS3.
"A few of you hardcore Street Fighters out there said that there was minor input lag in the controls of Ultra Street Fighter IV for PS3. Well, don’t worry: We’ve eliminated it to make the PS4 edition the ultimate version on any platform!"
