Running the same database on these two platforms gives dramatically different
coplanar rendering results? Here we go again ... (hi sharon ;-)

If you're using displacement, make sure you have a 23 bit depth buffer on the
Onyx2. there have been problems where you don't get the FB you ask for ... see
Rob Jenkin's previous posts.

Try using STENCIL mode as a work around. It's not too much slower on IR. Enable
it via the OpenFlight loader mode:

{
    if ( strcmp( pfGetMachString(), "IRL" ) == 0 ) /* ONYX2 IR */
        pfdConverterMode ( "flt", PFFLT_LAYER, PFDECAL_BASE_STENCIL );
    pfdLoadFile( "large.flt" );
}

Regards.
