There's much happening "under the hood" in messagepassing operating systems.
Each time the statistics are updated on screen, Windows needs to do a few
messagepasses, clipping, etc.

In addition, Windows was designed to enhance visual feedback rather than
application performance.


....but OTOH, with a multitasking system, I find that raytracing _seems_ to
go faster than with a singletaksing system (In reality, it never will),
mainly because I can do other things while it's working. In addition, WinPov
will let you see a render window so you can see it something has gone wrong
with the scene.

With newer version of Windows, the overhead will just get larger. Either get
used to it, or boot "plain DOS" and render your large scenes using MS-DOS
versions.
