Without commenting in any way upon the speculation regarding confidential
information, I would like to correct your evident misunderstanding of the
capabilities of the enhanced Denise vis a vis flicker fixer.  If anyone
doubts the wisdom of Commodore's newfound concern for confidentality,
they need only consider the confusion about the "non-interlace chips",
touted for two years and still undelivered.

The basic problem of the Amiga display is lack of bandwidth.  In order
to produce a 640 x 480 non-interlace display the enhanced Denise is
limited to four colors from a palette of 64.  Since all of the chip
memory bandwith is required to obtain four colors, performance will
suffer.  A non-interlace workbench screen with performance similar
to the current wb (alternate memory cycles avalable to the CPU)
will be limited to two colors.

Flicker fixer has no effect on performance and supports all display
modes.  It is, and will continue to be, the best approach to high quality
displays for the Amiga 2000/2500.
