Lots of ppl ask this to themselves what ping is, so i will tell what ping is.

Imaginate that you live in the USA and the owner of the server lives in China.
If you join to that server, your *Ping* should be arround 300, and when u join ur game starts laggy a lot *(slow moves and pc comes slower)*, making impossible ur gameplay.

So when *Ping* in a server is arround 1 to 150, your game will not lag, but if u got a ping more than 150, your game will start lag.

*Ping is how far or close you are from the owner of the server*. (Ping depends too, of your internet conection speed).
