You cannot, in anyway reduce lag without changing your game options or spending money. Lag is not a thing Badspot coded in to piss people off, it is like peeing. You may hate it but you can't stop doing it.
Either spend money and get something better then a toaster, lower your graphical settings, or quit playing completely.
Oh, and may I suggest you stop acting like a complete idiot? It only results in your key being revoked, meaning you can't play anymore and basically loose 20$.
