The human eye can detect changes at around 20 Hz. Your peripheral vision is a little more sensitive to movement, say 25 Hz if you're lucky. Most monitors have a refresh rate of 60 Hz; if you have sme fancy gaming one, and have a graphics card that can drive it at that rate, you may get 120 Hz. A latency of 6ms corresponds to a delay of 1/166th of a second, i.e 166 Hz. I can pretty much guarantee you won't be able to detect that delay with your eyes, or indeed any of your senses, no matter how much of a committed gamer you are.
