Some people seems to have problem with laggy lobby before even enter the game. Is it someone else that have this problem in the writing moment? I never had any problems before but it seem to overflow the computer with info so it start to lagg and in the end stop working, and this even before entering a game.
It never lag for me normally not even ingame.
I play on the european server
Same.
the lagging started after recent update.
I’m in NA server.
Hi:
This forum is for technical support on Blizzard’s Legacy Games – old games such as Diablo II: Lord of Destruction.
Starcraft II is not a legacy game… and it has its own dedicated forums:
Same here. when the custom games start it does not lag, but inside arcade lobby its very very laggy.
Re-read, very very carefully, the post just above yours. 
i have also this issue. Last time i could play normal it was on tuesday evening.
On wednesday i coudl start sc2, but then it freezes. I cannot logout of sc2, or switch to my normal windows desktop.
I can reboot or logoff to windows. And then logon again, but not use sc2.
i tried some old idea’s but it did not work: Starcraft 2 startup suddenly slow
I guess its because of an update of the battlenet launcher.
