Also, graphic-wise my MBP hates this game. While dying nonstop last night, the game defaulted to the highest setting. Lag, disappearing mouse, etc. Headache mania! Finally got it down to low settings this AM, which is a bit ugly.
Your older iMac should play it better - it has more GPU power...
I'd love to play it but all I've got is a 2010 MBP. Definitely keeping this game in mind when/if I ever upgrade.
Yes sadly you will need to upgrade - OpenGL 3.3 GPUs like your Nvidia 330M don't support the required minimum rendering features for UE4 under OS X.
Depending on the Mac, it could be quite ugly.My 2011 MBP will barely play it on low settings.
....
This article claims that game performance will be improved by the time it hit retails. Maybe then my MBP will play it better.
Unfortunately your MBP, which presumably has an AMD 6750 or 6770, is not supported by Metal - only Macs from 2012 or later are. Also as I mentioned on the other thread - don't believe performance claims for Metal that are too good to be true.
