The clip plane behaviour is to be expected, z precision is 'spent' between
near & far distances. You should make the near clip as distand as your
application allows.

Also on Infinite Reality you should enable multisampling, get a
multisample visual and use pfAntialias. This will have the side effect
of using 'compressed' zbuffer.

You should also select a visual with more zbuffer precision if one
is available.

The subface behaviour would exhibit problems if your pfLayers use the
PFDECAL_BASE_DISPLACE method.

Try PFDECAL_BASE_STENCIL or PFDECAL_BASE_HIGH_QUALITY to fix this.

Cheers,Angus.
