if you run with -verbose then it will tell you which graphics card it's using.
Video: Monitor 65537 = "\\.\DISPLAY1" (primary)
Direct3D: Using Direct3D 9
Physical width 242, height 346
Direct3D: Configuring adapter #0 = Intel(R) HD Graphics 530
RawInput: APIs detected
If it's using the 750M then it may just be too slow, or it might be using main ram to pretend that it has more ram than it actually has (an old nvidia trick, which on some gpu's can be disabled).
nVidia optimus is the standard way of switching between intel & nvidia chips. The nvidia just outputs into the intel framebuffer, so it really just works as a display accelerator. Earlier laptops used a more complicated system where each chip was powered up and hooked up to the video out, which required specific device drivers from the laptop manufacturer (who never bothered keeping up to date with nvidia releases). I don't know which method Apple used, but it sounds like it's not optimus.
