Hi,

I'm programming in Windows on a 25MHz 386 with 3MB of extended
memory.  I've got a Hercules Graphics Station card with the extra 2MB
of memory and the TIGA 2.0 drivers.  I've only got a plain DELL VGA
color monitor, so I'm using the 8-bit TIGA driver (640x480x8).  It
looks pretty good: 256-color PCX and GIF files are quite amazing.

This is the problem:
I'm writing a program which will read in a bitmap in either TIFF,
PCX, or TARGA format, convert it to a Windows DIB, and display it in
a window.  I can do the conversion OK, and use SetDIBits() to write
to a memory device context, in 60KB bands.  The problem is that this
takes about 30 seconds per band!  In VGA mode it's only a couple of
seconds.  I can't wait 5-10 minutes to see an image when I'm doing
program development.  I talked to Hercules, but they didn't offer anything
useful, and seem to think that it's the Texas Intruments chip at
fault. 

So, to summarize (what, already?):

	- should I be doing anything different with my DIBs?
	- is there another 8-bit driver out there?
	- is the 16-bit driver any better?

I've seen a lot of hype for the Graphics Station card.  However, my
impression is that the performance is no better than any SVGA card,
at least with my vanilla monitor.

Thanks for any wisdom!

Phong.
