Invisible people

[Lonestar47]

Whenever I play assault it's twice as hard when I'm on the red team because the blue guys pop up out of nowhere because I can't see them! I can still shoot them if I just happen to know they're there. I don't know how they turn invisible but they do and it makes the game way too unfair! How do you become invisible?!!!!

You are probably talking about a line of sight. When players are a distance away from you they start to turn invisible. Either that or you are talking bout the lag problem where you are barely able to see them, the player is "flickering". That is lag related.
