Legend86,
We don't have a measurement for game lag. Most game systems will connect to our sets and work just fine, although some lag (due to picture processing) may cause lag.
This model does have a "Game Mode" option, which disables some of the additional picture processing and lag, making game play more "instant". That feature is available on any of the HDMI inputs.
Thanks for your interest in Samsung products.
