>>715548051 (OP)peekers advantage in cs has been debunked. It only seems like it's there because the client gives instant prediction feedback. Someone did a video demonstrating this with high ping awp vs low ping awp, with 1 peeking and the other holding angle. They tested both sides of this (high ping peeker and high ping holding) and compared times from both sides manually to determine who actually shot first, and outside of some extreme lag spike edge cases, the server gets it right. But because the client gives instant feedback, it feels unfair when you clearly heard your own shot first yet you're the one who died.
