When a player has high ping, it appears to him and to an observing player, each, that the other is warping.
You can make an attempt at minimizing this effect by experimenting with the values for smoothmove and smoothdist -- but I don't fully understand how those work. Basically (I mean very basically) they tell your client how much to "guess" about a player's position if info hasn't come from them for a while. The up-side to a high number is that you have more time to frag them before they go transparent and salute; the down-side is that when they come out of the lag spike, there's no telling where they could be.
