Though I run Win95 on my machine I've never downloaded the Windows version of 
POV. The download time isn't worth the multi-tasking I don't do anyway (with 
POV anyway). I run POVDOS in a DOSBox on Win95 with as much CPU time and 
memory alotted to it as possible, only allowing me to ALT-TAB out to use the 
calculator or Spatch.

I don't run a Pentium and I don't have 16MB of RAM (let alone 32 or 64 that 
most Win users have available to Windoze). POVDOS runs great, the only limit I 
really run into is the Max_Trace_Level which under the DOS version only allows 
for about 32 levels of trace... but I've not really needed more than that yet 
(anything more would keep my little AMD busy for days).

Eventually I'll get the latest Bill Gates machine running that Win98 thing 
(yuck) and this computer will get some minor upgrades allowing me to run Linux 
comfortably. At that point I should be running both the Win version as well as 
the Linux version, I also plan to network the two computers together so I can 
share files. Stuff that's just too slow for the AMD I'll do on the new 
machine.

DOS isn't dead, there are 3 or 4 DOSes still around (even if MS won't sell it 
anymore), people all over the world still use it. Internet access is mainly 
what pushed me over to using Win95 full time, but even then I used a DOS 
program for 1/2 of my access (Arachne) because I only had 4MB of ram for a 
while.

Sorry any spelling mistakes, my newsgroup reader doesn't have spell check.

Duh, yes. If you really want things done fast, Windows shares resources with
other programs, which slows down your trace. Read the Windows documentation.
Also, a DOS version can run on other platforms which aren't supported, but
run DOS programs, like IBM's OS/2.

Uh, last I checked Windows Nt can run DOS proggies in NTFS. It's the
operating system, not the file system. Accessing HPFS partitions from DOS,
you're on the money there.

If so, answer me the following questions:

1. In Windows, how come DOS Quake gives me a 5 FPS framsboost over true DOS
(6.22)?
2. How some people report WinPOV faster then DOSPOV?
3. How can you prefer DOS over Linux? ;)

  Actually dos-programs have to share time with 16-bit code such as the
timer interrupt. Switching between 32-bit protected mode and 16-bit real mode
18 times per second can slow things down noticeably.
  Under windows this changing is not necessary since the timer interrupt is
handled by windows in 32-bit protected mode (or at least I suppose so).

: 2. How some people report WinPOV faster then DOSPOV?

  Because MSVC++ can optimize code better than watcom for DOS.

DOS is just better for some things.  Go see the answers to last week's 
Slashdot interview with the leader of the FreeDOS project for some
examples.

  What things? I can't think of any.
  (Ok, there might be some DOS-programs which are not available for Linux
right now, but that doesn't make DOS better than linux.)

  Disclaimer: I use the dos-box (well, actually the 4dos-box) a lot when
I use windows. Some things are a lot easier to do in the command line than
with windows explorer.

I'm going to use your own words against you -

"  You also must be able to boot from a floppy disk. Suppose that your
computer gets infected by a virus. You have to boot from a clean floppy
and run a virus scanner from that floppy disk. You can't make a clean
boot to windows from a floppy disk. If you boot to windows, the virus will
also load itself to memory. If it has some sort of stealth capabilities or
something like that, there you are.
  That's why f-prot is still a dos-program."

See ! There are some things you can do better in DOS than in Windows :)

Specifically, things that don't require the support of a full 32-bit
multitasking, multiuser operating system, like flash BIOS updates or 
lots of embedded and other industrial applications.  Go read the 
interview; it's very informative:

Maybe the windows DPMI is better than Q's?

>2. How some people report WinPOV faster then DOSPOV?

What compiler is used for each? What settings? Is parsing an issue?
All things equal, windows is slower than DOS. Even the mouse
interrupts take some CPU time let alone the gui and all other things
it's doing behind your back.

>3. How can you prefer DOS over Linux? ;)

A mystery yet to be unveiled.
