I have a black macbook that I bought about a year and a half ago it has 2 gigs of a ram and the 2.16 gig processor. I have road runner cable internet which downloads at 21 megs per second and upload of 1.2 megs. Yet when I try to play warcraft 3 online after about 5 mins when I'm in a game it lags like crazy and wont go away I can restart the game or computer 50 times same thing is it my internet? computer? I cant figure it out.
