I received my copy of SC2 yesterday, had no much time, so I just tested it for half an hour. These are my system specs: MacBook Pro 15" (Early 2008) Intel Core 2 Duo Penryn 2.5 GHz 4 Gb Ram nVidia Geforce 8600M GT with 512 MB The laptop is attached to an external 21" ACD. I tried SC2 on the latest Mac OS X using both the following graphic settings medium - 1200 x 800 (suggested settings) low - 1680 x 1050 In both cases the computer gets very hot since I saw the GPU reaching 78-80 Celsius. And that using a cooling laptop pad. Is this normal ? When I play WOW it usually doesn't go higher than 70-72 Celsius even in 25 man raids. I must say that in WOW I capped the fps to 30. I'd like to know about your experience with this and if there's some trick I can use. Thanks.
