GRX 2.0 is still a beta graphics library, and has not been actively
supported for a long time (nearly a year now). It may well have
problems in speed and/or low-level routines like page flipping, but I'm
the wrong person to ask.

Took you long enough to get here. :) It seems that the vast majority
of DJGPP success stories come from folks who've used the Allegro
graphics/game programming library. It's available from SimTel in the
'v2tk' directory, and has been shown to be a hundred percent faster and
more reliable than GRX. The only problem is converting your code to a
different interface.
Don't get me wrong - there are also quite a few GRX success stories out
there, so I'm sure that somebody here will be able to help you. :)
