Hi, I'm on a Macbook Pro 15", brand new out of the box, files manually transferred. Right now, at 1680x1050 I get a 30 FPS average, with 35-40 at the mineral line and mid to low 20's during 1v1 large battles. On high, this goes to 40-50 at the mineral line, to 30-35 during big 1v1 battles. Medium I get 70-90 FPS at the mineral line, and 50-60 during big 1v1 battles. Low is not even worth talking about, triple digits are annoying. This is all at 1680x1050. I'm experiencing maybe a 3-4 FPS increase? This things gets LOUD though... ...No way around it though.
