I play SSF2 on a 2.8GHz 16GB RAM Mac and my internet works fine most of the time but I keep getting input lag every time I go on SSF2 online (or at least for the first few minutes of the match). Most of the time my opponents don't have this input lag as they can react to my movements with perfect timing. It's super bad at the beginning of the match too, because I'll try to short hop aerial and my character just jumps completely over the opponent, giving them a perfect opportunity for a punish. Is there any way to reduce input lag other than putting the graphics setting on minimum?

Oh and there's f*** lag spikes every 2 seconds

You can reduce input delay when creating an online room i believe, but doing so will make lag spikes more frequent (it's better to reduce input lag only if all players have a decent connection), either you'll have to put it on high delay (but i think less lag spikes), get better internet connection, or just... deal with it
