  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.

main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/
