I know this probably isn't the proper space to ask this question but I've searched for so long and found nothing...am I the only one with an indredibly slow client? It can neither be performance nor my connection because in game everything runs smooth, it's even the most basic stuff that doesn't require any interaction with the servers like typing a champ name in select, talking about like half a second to multiple delay on EVERYTHING

Really don't wanna be that guy but I think si stands for - source identifier, correct me if I'm wrong though.
