I'm totally sick of this. I can't do shit while i am lagging like that and when it finally stops lagging i am in most cases dead. Even as an archer now.
It is map- and server-related, but it can happen everywhere. And it's the upload-rate which fucks the game up (I checked that now...download is never the reason for those laggs). Settings do NOT matter. I can play on the highest settings for hours (Ok, that is a really rare case...) without lagg or with dx7 and all that low shit and i can't play 1 minute without moonwalking through calradia.
But why the hell is the upload-rate so freakin high sometimes? I just don't get it. Shogun 2 works fine online, css, tf2, all those mmorpgs i played are fine, too.
Fyi: My Upload is 5kb/sec or so (Dunno exactly) and everytime the laggs occur the upload goes up to that maximum.
