Date: Sat, 22 Feb 1997 14:34:21 -0800 Organization: University of Washington Lines: 20 Message-ID: NNTP-Posting-Host: saul2.u.washington.edu Mime-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII NNTP-Posting-User: hyena To: djgpp AT delorie DOT com DJ-Gateway: from newsgroup comp.os.msdos.djgpp 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?
