I own a Macbook Pro 15" i5 2.53 GHz model. So far it has been a great laptop, but while playing this game- http://www.digminigames.com/titanic-kungfubot-offensive/ I've been getting ridicolous amounts of lag recently. It worked fine a day or two ago, but recently its been around 3 seconds between when I push a button and the execution of the button in the game. It works fine with my Lenovo (i3) laptop which is using wifi too, so I don't know what it is. It's just one game, but I've also heard a "click" from my laptop occasionally for a while now. I heard this could be my harddrive going, so thats why it worries me. Any ideas to see what the problem is and how to fix it?
