Well, if it has been happening for a while on your laptop then I guess it may not be a laptop you should be trying to run Toribash on. What kind of hardware and specs does it have? (Also it might be it having trouble loading all the multiplayer servers, which in itself could be down to a slow net connection)
I'm a game developer for other games.
Ping me if you have a query or general question unrelated to this game.
