I'm playing on a MacBook Pro Retina, late 2013, and it's got a fast processor, lots of RAM, and the very decent Iris graphics on the Haswell chip. And yet, Hearthstone blows through my battery at a ridiculous rate, and my laptop gets hot when I play it. I have my graphics set to "low".

My thought is that this is a card game. It'd be nice to be able to turn off all the CPU-intensive stuff and just play it like a card game. It'd be a nice option anyway.

Thanks in advance.
