I'm programming a very nice game with DJGPP and allegro. I use SVGA 640*480*256 colors, so graphic looks good. But the problem is the double buffering. It's just too slow. Example : BITMAP *buffer = create_bitmap(640, 480); clear(buffer); while( game_continues) { // some drawwing on the buffer blit(buffer, screen, 0, 0, 0, 0, 640, 480); } That is a the only way I can think of, but itsn't fast enough. So is there any faster way to do that 'blit(buffer, screen, ...)' ??? Tuomo Turunen
