Running well on my 2013 15" MacBook Pro i7 2.2ghz 16gb and Intel Iris Pro graphics. Pretty much base model. I'm running it on low/medium settings at 1440x900 and its smooth and enjoyable. I'm playing with my xbox one controller emulated to appear as a xbox 360 remote as it won't recognise it otherwise it. for this I used Xbox360Controller app which is free. I was going to return this as it wouldn't work for me at first but just as I was writing the return details it came to me to try dropping the resolution and bam it worked a treat. I bought this for when I'm flying and it makes the hours fly
