What did you have running in the background? Windows 9x gives much more time to DOS tasks than Win32 tasks. Or did you run the DJGPP version from plain DOS? How well optimized is driver support for your card's fill (aka solid hline) function? There's a lot more overhead on some calls under plain old DOS than there is on WinDOS. You might want to take this up with the Allegro mailing list: http://www.talula.demon.co.uk/allegro/maillist.html as they likely know much more about Allegro (especially the non-DJGPP ports) than we do. -- <O ( \ GNOME vs. KDE: the game!
