I've been playing this game on and off since world 2 and for the first time I'm experiencing some horrendous input lag/delay that seems to have nothing to do with my connection to the server.
For the past few weeks, I've been able to run the game just fine up until the recent patch. When I launch the game, it's fine for a few seconds then suddenly I'm treated with 1~3 second input lag.
I tried restarting, reinstalling java and using different clients, and it hasn't gone away. Any ideas what might be causing this?
