I found very little if any lag at all during the online sessions I played. The voice communication worked perfectly and it definitely was a ton of fun to play. I think that is the bottom line with this entire game. Its so much fun to play. You have to love a game where all you have to do is put the gas to the floor and go without every letting up. Now of course to shave time off your times you will want to learn to brake a little bit. But when you are out to take out the competition just put the gas down all the way and go. Be sure to smash into them, land on them or do whatever it takes to wipe them out. They are not your friend during a race. http://naildbiter.com/Ei9S8
