I don’t have an Xbox but I do have PS3. I am now using Clear internet service for my play station, playing GTA4(EoLC), RE5, Resistance 2, etc... and no lag. I played 5 hours ago and the connection was solid, continuous, and constant.
Even in harsh rainy, windy conditions here in Houston the connection is consistant good for gaming. Make sure you check your location make sure it is in the CLEAR BEST CONNECTION range to get the same results.
