I've put about 12 hours in on my late 2013 13" mbp. For a decently sized-city (10k+), there aren't noticeable performance issues at full-screen and mostly 'medium' display options. Your fans will get a workout and you get about 30 minutes of battery life off the charger, though.

10k is barely scratching the surface. 50k is where it gets interesting.

I've got an Air with Intel HD 5000 and it runs ok. The framerate is a bit low, but for a simulation it's fine.

That's good to know. I bought it for my pc but wouldn't mind getting a copy for my mb air.

copy? unless you want to play on two machines at the same time, you don't need it, it's steam after all

Good point. I've never played a steam game on anything but my pc so I wasn't aware I could just log into my steam account on a different computer.

I'm wondering the same thing - does the spec saying that it doesn't support Intel graphics just mean that I'd have to dial down the resolution, or is it a hard stop?

I have a ThinkPad 440s, which is a beefy machine in other respects, but has integrated graphics. I can't currently play the game due to rendering glitches :/

Are you playing through Steam? I had rendering glitches on my MBP until I turned off the Steam overlay. Everything has worked fine since.

I am! I'll give that a try, thanks!

It doesn't support integrated graphics on my Macbook at all. Luckily I have a PC as well. There's a chance it would work, but I wouldn't bank on it.

It crashes on start for me on my MBP 13, so I'd say no.

What GPU does your machine have?

Thanks! I think the Iris 6100 is a bit newer than that. Still, gives me pause.
