After some long years of lagging and hardly even able to move my in-game mouse because of the intensity of it, my computer screen finally broke. (Though it was very old, maybe 10 years or so?) and I got a new one! So then I go online, jump into the game of TEF, and there in front of me, I realize the strong absence of a nasty thing- the lag was gone! It was perfectly smooth, I suppose the other computer screen was much too old..and so I'll probably be much more active from now on.
