I think I've issued this complaint before, and it was claimed fixed. Or at least something like it.

On my MacBook pro, the not eye graphic system is quite slow. I've tried the Open GL mode on or off.
It routinely hits 100% cpu usage on default settings. (still on the 15 fps mode)
Some areas have a frame rate that is nearly unplayable, like forest wilderness areas and the Tower of Eternal Flames.

I suspect there is some software rendering occurring, rather than using the video chip.
Missile fire is painfully slow too.

I find myself wishing for a non-animation mode, where the display only changes on input or similar action, rather than constant background animation.
It also uses the battery up much quicker, even when not actually moving.

(if there are some settings I haven't figured out, tell me - then put the hints into the FAQ / readme / help system.)
Music and sound are off too.
