Hey I just got back from a 2 month vacation and decided to finally play wow on my 20 inch ACD. However I'm having a problem. With the mbp screen lid closed, running it in windowed mode, with all settings put on minimum, and with no other apps open its hardly playable when compared to it running on the macbook pro screen with itunes, firefox, and iphoto open. I thought that there might be some difference between the two but this is pretty bad. thanks for all help in advanced. ( its the mbp shown in spec)
