According to the folks over at Kotaku, who talked to a SEGA representative via e-mail, have finally confirmed if Virtua Fighter 5 Ultimate Showdown will have roll-back netcode. It won’t. This might be the biggest disappointment to fans looking forward to playing games with someone across the country.
It seems that the game will be re-using the old Virtua Fighter 5: Final Showdown netcode, which at the time was well received but now more people are asking for rollback netcode in fighting games. This movement has spread so far out that SNK has even went back and updated their old classic games with rollback netcode.
Though just because a team uses rollback, doesn’t mean that the game will not have lag or other issues. For example, Street Fighter V uses Capcom’s own rollback netcode and I personally have had way more smoother games in Virtua Fighter 5: Final Showdown back in the day.
