I have had nothing but better and better game play now with the MAC 64 -bit client. Between this and Apple, who I sent copies of all crashes etc. I have rarely experienced any lag nor crashes. It used to be, I could not run with a squad in WVW because it would just slow down so bad, like flip cards for old cartoons. Anytime there were large groups of people in any area I avoided them to be able to keep playing. I was never able to run Team Speak and GW2 at the same time or CRASH.All great now!! =) <3 FYI I also play only with mousepad! I have a pc which I can play on as well but I am useless with the mouse!
