I get pings as low as 25ms cause I picked a relm with a server very near where I live. At 25fps a frame is rendered every 40ms. But there is a ton of extrapolation as to the location of characters, you computer will calculate the direction and rate of movement even if its not updated by the server, up to a point. It dosnt stop rendering just because it didnt get data from the server in the last 40ms.
