A:Answer I game using mine on a regular basis and I have not noticed any input lag at all. Be sure to read the manual thoroughly though, as there is a specific input that you should use for hooking up a game system to decrease lag on Samsung TVs. Also, you can adjust setting in the menu systems to turn off some dynamic picture elements which will drop lag even further. Straight out of the box though, I had no problems at all. Unless you are a super human able to perceive a 5ms difference then you shouldn't have any problems. Looks great on my end playing all XBOX One games.
