Do Mac ports of PC games such as Batman Arkham Asylum, have PhysX enabled? I know that Nvidia has released some PhysX SDK's for mac not too long ago, but that's all I know.
Got a tip for us?

Nvidia PhysX Support for games on Mac?

Assume there is... you still can't take advantage of it since you need a secondary GPU dedicated for PhysX crunching.
Oh ok. Are you sure? Since I've messed around with Nvidia's rocket sled PhysX demo on windows 7 via bootcamp and it seems to run pretty well on my new MacBook Pro 15" (non-retina). The fans were noticeably loud though, which is understandable for such a graphically intense demo.
Well, you are using a mid-level GPU to do high level stuff at a high resolution; not to mention run a set of instructions which are hardware demanding. The loud fans and high heat would mean the GPU might have throttled due to thermal limitations.
Well, yes if you want the best PhysX performance. Normally, in the past people recommended the GeForce 9800 GT as an add in card for PhysX computation. This was in addition to the already in place discrete GPU.
I understand that PhysX's performance can be much better when having a second card dedicated to that task, but it still can be done decently well with just one card. You won't get super high frame rates, (my FPS momentarily dipped in the most intense part the rocket sled PhysX demo with maxed out graphical settings) but that is still playable in games, especially if some other settings are toned down. I was just wondering why Mac games haven't enabled this feature in their versions of PC games featuring PhysX. I guess I can see why though, since many Macs don't have Nvidia based GPUs. Either way, it would be nice to have this feature as an option.
On modern GPUs, PhysX can be run with a single GPU with little performance hit.
The 650M in the rMBP is fast enough to run PhysX in some games. In Batman: Arkham City, I can run PhysX on medium with high-ish settings at 1920x1200 and get 30+ FPS.
I have no idea if PhysX libraries are available on Mac, though.

Can you share your Batman: Arkham City configuration?
Lots of people have had problems getting Batman: Arkham City to work at all or well. Can you share your configuration for it?
It almost seems like someone should setup a site for game configurations for the rMBP...
Ciao!

PhysX can be even done on the CPU. It's definitely faster if it's done on the GPU though, even 1. The days that a second dedicated card was required for it are long gone.
i believe the CPU can be used for PhysX, which may be why your computer fans where going wild, since the CPU is the hottest component in the computers
