What? 1/6 of what you expected? How do you expect Allegro to blit at 300fps?
Your nearptr code will not do any better than 50fps (if even that). If you
can do better, I'd be surprised.

And regarding your other posts, you won't (don't want to?) post your
assembly code that you say keeps crashing. How do you expect us to help if
you if you won't post the code?

BTW, VESA programming in DJGPP is not difficult at all. Look at the DJGPP
User's Guide on the homepage (http://www.delorie.com/djgpp/) for a couple
great articles written by Shawn Hargreaves about VESA programming.

Cheers,
