MBA 11 with i5:
runs pretty nice - most of the time 30 fps. A little less with the view of the city. Minor fps drops in fights.
are you sure you're not talking about Arkham Asylum ? Arkham City requires Windows and a dedicated Graphics Card.
Batman AC plays fine on my 13" Air at medium settings and 25-30 fps. My card is integrated.
Regarding to your sig, you got the Nvidia graphic (2010) which is NOT integrated.
Sorry for the OT question but just curious, are there emulators out that would work on the MacBook Pro and if so, are there good controllers out that would work with it? I'd like to play some older SNES games if they're available.
On my iPad when I had it jailbroken I was able to download and play an SNES game. But I wanted to get a Wiimote to play via a controller. Playing on the touch screen was too hard.
I've used emulators for NES, SNES, and Sega Genesis. They all worked pretty much flawlessly. I was able to use a USB controller with all of them as well.
This is the controller I used:

With NES, Genesis, and SNES you can't use a controller that is made for modern games and thus has the two joysticks. The joysticks mess with the emulators and never work right.
