A:
I am not certain on the exact lag specifications; however, I bought this TV for the exact same reason. I bought it for the price, size, and for gaming. I play Madden, Infamous, Minecraft, GTA5, Fighting games, COD-AW, COD-BO2, COD-MW, COD-BO1, and many other games and it works very well for that. I actually noticed with the game mode ON it enhanced the picture and I could see the darker areas that I could not notice as well before. I am not sure if that helps you but that is what I can tell you. I have had it for 2 weeks now and that was the main reason for the purchase. It works with 1080p also. I can only tell you that it has worked decently for the gaming it has been used for thus far.
