This port sucks.
My rMBP results for windows and mac version:
- Mac: 1280x800, Low details, AA disabled, low shadows, Vsync disabled: 20-30 fps.
- Windows: 1980x1080, High Details, 16x anisotropic, High shadows, Phsysx enabled, Vsync enabled: 40-60 fps.
Sucks is a strong word. Read eddeduck's posts - this game relies on driving the GPU in every way GL doesn't want you too. Falling off the fast path under GL is bad - under Apple's it is near fatal.

Just for comparison with the PC version you posted I also tried:

Wine's performance appears to have gone backwards while native Mafia 2 is much better post-10.8.3 on the NV650M.
