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. > 5) success stories with DJGPP (gcc for DOS) graphics programming. 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. :) --------------------------------------------------------------------- | John M.
