Greetings One and All !
I have always presumed that the settings for render and gui
priority were only in affect when used in a multi tasking
enviroment. That is to say if I have Pov rendering a scene
and want to run other programs, with Pov running in the
background, then I can use these setting to set the level
of cpu and gui priorities I am willing to give each program.
If Pov is the only program running then these settings are
meaningless and all of my systems resources are dedicated to
the task. I can't imagine that having the gui priority set
to highest, with Pov the only program running, will greatly
if at all, impact the render time of a scene. Especialy if
that scene is going to take a long time to reneder anyway.
Is there fault in my understanding of these setting and if
so what ?

Yes. The fault lies in assuming that nothing else is running.
Even a very clean machine has at least one other obvious task
running; that would be Explorer. Also, there are a few
normally-invisible system threads as well. For example, my
current win98 environment has 4 Explorer threads, 8 Kernel32
threads, 1 mprexe thread, 1 mmtask thread, 1 taskmon thread,
and 1 systray thread in addition to the things I can trace
to apps I consciously ran (such as McAfee VirusScan). Many
of these threads are at 'normal' priority so they get the
same-size timeslice as does POV running at normal priority
(assuming they want input or have something else to do.)
