I made a program under Linux last night which had I think 10 guys (80x120)
flying around the screen in a sincos pattern over a background of the
palettes (like each horizontal line is color c where c is 0 through
255 then to 480)...
So it's 640x480x256.
Then I scroll the background downwards.
Short simple program.
I test compile it to DOS and even without the background scrolling it's
terribly blurry...
I had to remove all but one of the guys in order to get it to work.
It works perfectly under Linux without background scrolling and a little
jumpy (you don't notice unless you look) with the background scrolling...
I have P166/64 with 2MB S3 Trio...

So the question is, what is the problem here?
Is the problem something I'm doing?
Is it the svgalib 1.2.7 (this is djgpp's svgalib I think)?
Is it inadequate support for my specific card?
Or is it just DOS?
