I noticed something. At the first hours of the day, there is nearly no lagging, but just when afternoon-midnight the lag becomes a beast hunting players.
I guess that means it is not a problem from us, it is server-sided, isn't ? If OOO servers can't handle a big amount of players then why don't you make more servers ? Don't tell me that you don't have enough money D: I am sure the millions of cash that people spent are still there. Not enough people ? Recruit more workers, this game is growing large OOO, you made this game awesome, please bring more workers >_>
ye'll need to restart everything including yer computer and close yer router, unplug the ethernet cables, every single of it, and when ye're at yer home screen of yer computer, check for any programs that interrupts yer connectivity and close them, then ye may boot yer router now. when the internet is available, plug ONLY yer ethernet cable to the router and login to steam. (be sure ye're on the library section or the friends section, avoid stores and community and big picture.)
try booting sk and login, if ye enter ready room less than 5~7 seconds, ye're good to go, so does yer event hub can response about like that, faster than entering ready room. then ye may now replug in yer routers and see if it still okay to play.
if everything is out of the question and does not work, check yer network if anyone outside of yer local area connectivity is sharing network with ye. sometimes it isn't just us but them. or so.
if nothing works, im out of ideas.
(ps. i don't recommend using gamebooster unless yer graphics are not great for sk)
