At 14 I discovered that tiny response times are essential by observing terminal echos from a TCP client and server connection. I could clearly see a 50ms difference, down to about 15ms if I recall correctly. It wasn't until years later that I discvered high response+refresh monitors and from then on anything under 120FPS is just laggy if it's a game.
