Florida USA. For me the lag varies greatly depending on the hours I play. I find that I can get the most stable matches between 6 PM ( 11 PM Your time) and 12 am (5 am your time)
Anything after 12 am usually lags a lot as the people I am playing are probably in Europe, Asia, Or Latin America. The ping is probably very high when connecting to these peers. This is considering that the lag is legitimate. There is video proof on youtube of people lag switching in Killer Instinct online. Someone complained about it recently on the last 8bit beatdown, and maximilian actually recorded someone on his stream lagging to gain an edge
These people probably utilize a lag switch or a script of some kind to cause lag spikes in certain key moments, maybe even torrenting or an ftp server as that that will flood the connection. The less obvious cheaters cause the lag surges sporadically and in key moments, like getting a roll back lag advantage during a combo, using lag to interrupt your combo or opening, getting you to consistently lock out on timings etc. Some people even lag during jump ins to the point that the roll back and missing frames makes them unpunishable.
The matches then devolve because you have to play simple to compensate for the rollback. Then if you take into account how precise you have to be with counterbreakers, and how not every character benefits the same from the combo system in terms of damage, and you have a different game online than offline, where tiers change and tactics that shouldn’t work begin to work.
KI never had these issues before the ping increase. But I guess thats the price we have to pay to find more matches. A few simple matchmaking filters would help alleviate some of these issues. Region, Connection strength. voila, presto. Almost every fighting game has these basic features.
EDIT: Actually in season 1, when one of the p2p the connections surpassed the ping limit, there would be a desync. Essentially your opponent would drop and disconnect and you’d be left playing a dense A.I. As opposed to the lag fest and rollback you must endure now. A good way to tell how laggy a match was is to go back into the replays. Usually when the replay makes no sense the match was pretty terrible in terms of lag.
Also, when I say lag, I mean rollback, not input delay. I feel I must point it out because some people think lag means input delay. I mean rollback, missing frames and things of that nature.
