Hi guys, I've just installed gfxCardStatus in my 2011 base 15" and I wanted to put my thoughts on it. Write now, I am just surfing the internet, plugged on power, however I noticed that the 6490 is on. Is this normal? Are there some rules that are causing the switching among the graphic cards? Because from what I understand , surfing the internet (actually posting on this site only) it's not an excuse to have 6490 running. Something different now, i bought Civilization 5 but my desktop pc that i use for gaming is running too slow after turn 250 or something. Recently i noticed in the steam updates that Civilization is supported for 6490, so despite I am not using my mac for gaming (only for fm2011) i am considering of giving it a shot in my mbp. Any of you guys tried it out? Sorry for my lengthily post here (once again) Updating : Hm, after examining the gfxCardStatus it seems that some of google's chrome processes are causing the switching to the Discrete graphics. So, is this a bad programming from google , or it's normal for web browsers to be hungry for resources?
