I recently received my first apple computer but i am having problems with warcraft 3. When i start the game it run perfectly as to be expected but within about 45 minutes it get all choppy, about 2 frames per second or so. When i restart the computer and try to pick up where i left off in the game it continues to be choppy. All i have done is installed it and the frozen throne and installed all the updates off battle net. Not sure what i am doing wrong or if there are any setting i have to tweak. Thanks for your help. By the way it is a MBP 2.2 brand new this year.
