Masahiro Sakura revealed some interesting details in this  week’s issue of Famitsu, when discussing the netcode for Super Smash Bros Ultimate. Here is a translation from Siliconera:

 

– “1v1 is a very big element among the online modes; we made the input delay in the connection to have more aggressive values. Things like transmission interval and buffering are crammed in.”
– “Tangible details on the connection improvement were not announced, because no matter how much we improve it, the factors from users’ environments are bigger.”
– “Mr. [Katsuhiro] Harada from Tekken said that around 60% of all home consoles use Wi-Fi. But in Switch’s case, it would be more than 60%.”
– “There have been requests to show whether the opponent uses Wi-Fi or not, but it’s not like they can be rejected, so we cannot do it.”
– “It’s not like Wi-Fi is bad, but please kindly use a wired connection in order to have a stable match.”
– “There are also requests for a rollback method, and we did inspect it during development, but we passed up on it. The side effects were too big.”

What he means by side effects are not clear at this time.
