http://noble-press.com/2012/06/game-macbook-pro-retina-display-2012/ If u read that article towards the end he suggests that gaming on a retina dsplay will tax the GPU more than the normal displays would, even if running on same rsolutions. So he suggests gaming on an external monitor to fix the problem. But leaves it open ended and inconclusive on that point. Is he correct? Is gaming on a retina going to be worse even at same resolutions? Since one is using more pixels? Seems if that were true since it has 2x pixels it would perform half as well to normal same configed laptops. Note: they say there is 4x the pixels but only 2x resolution. I do not quite understand that, as the GPU is on the same res regardless of how many pixels the screen fills, they are seperate hardwares aren't they? Doesnt the monitor work seperatly from the GPU?
