On my MacBook Pro Retina (15") the performance in this game is really best described as terrible. I made sure the discrete GPU is being used. I tried it at first in 1280x800 resolution with all the visual options turned on (a rough equivalent of what the game is on PS3) and the game was chugging at approx 20FPS or less from the first section on. I tried lowering the resolution, disabling all the visual options, and it really didn't help much at all. Even at 800x600 and all options off, the resulting framerate is fairly unstable and barely ever 30FPS. For comparison, every other multiplatform game on this laptop runs much better than it does on PS3, but The Cave definitely runs much better on PS3. I tried the game under my Windows 7 partition, and the performance was far better (relatively stable 30FPS (or more, I'm not sure, but it was quite smooth) at 1600x1050, with all options on). So it's not the hardware, it's the Mac version of the code.
Is this normal, expected performance for the Mac version, or am I just particularly unlucky (or the game is incompatible with Retina laptops)?
