Hicolor (16 bit): multiply twice your screen width by screen height. Divide this into your bus bandwidth to get maximum frames per second. Or use a "dirty rectangle" approach: only blit what has changed from frame to frame. And there are faster versions: try using a FreeBE/AF or SciTechSoft Display Doctor driver; Allegro supports them. If you are on an accelerated system, keep your bitmaps in video memory. -- Damian Yerrick http://yerricde.tripod.com/ Comment on story ideas: http://home1.gte.net/frodo/quickjot.html AOL is sucks!
