Well, of course, try out different servers.
Also, if it isn't the servers, try turning your settings down a notch.
Go from 32-Bit to 16-Bit.
Go to the lowest settings (Not including sensitivity, etc)
Hopefully all works out.
I do get somewhat of an unplayable lag, and I'm sure it isn't my laptop/connection.
To fix this problem, you simply exit the room, and rejoin the game.
If that does not work, try a different server, if it's still not working, exit the game, and try once more.
It also may be a bug, and it'll eventually be fixed.
