This is only true for graphics modes too high for all of the graphics information to fit in the 256K video buffer. The 320* 200*256 information fits in 64000 bytes (even less than 64K), and you can fit *four* display pages in the buffer. >Sometimes its even faster not to use page flipping - than you >may address the whole 320x200 screen at once - draw your screen >in memory and do a memcpy afterwards! Again, this is only true for res modes higher than 640*400. -- Bill Moyer <ttk@rahul.net>
