Consensus is that the problem lies with the way PLIB handles the tracks
(ie large polygonal models) and the physics code taking up far too much
CPU time.

Whilst people have been poking around the physics code, it seems nobody
has actually seen nor solved that particular issue.

There are patches for PLIB that improve things roughly twofold, and
hopefully they will make it into PLIB sooner rather than later.  But
even then, the performance is no where near what it should be for such a
relatively simple game.  The only other way to improve things on this
issue is to break up the tracks into sections, but that's messing the
level designers about.  Really, Steve needs to grab PLIB by the scruff
of the neck on this issue and other PLIB problems, but he's publicly
refusing to get involved.  (Which is surprising, because if he'd fixed
them, then there would be no need for the current SDL dependency and
he'd be happy again.  *Sigh*)
