I was looking for some help on the mac version of Pinball arcade (steam). I recently jumped back over to mac after having a pc laptop and am having some issues with playing one of my favorite relatively simple games on steam. My pc laptop was an AMD A10-4600m 2.3GHz quad core (well AMDs version anyway) with Radeon 7660G integrated graphics. It was a modest laptop but played the simple games (and even some of the more demanding ones like Bioshock Infinite) I enjoy such as this one no problem, very well in fact. I would think this machine with a quad core i7 (which crushes my old cpu) and Iris Pro graphics (quite a bit faster than the 7660G according to notebookcheck) should be able to handle it? Is this just another case of Mac gaming not being as well optimized as PCs or is there a setting I'm missing?
