Well, if the behavior is the same in previous versions, your post is a
feature request...

Of course, if you don't output the image to file, the image file does not
have to be written and rendering will be faster.  Obviously, this cannot be
avoided if you want an image written to disk.

Information output takes time.

Maybe you should get a faster graphics card if scrolling is too slow? - On
the other hand, I have yet to see scrolling being slow, so probably your
system is having other problems.  Maybe your graphics card driver is missing
and Windos defaulted to the universal VGA driver?

You can easily edit povray.ini if you want such a default.

So POV-Ray is to magically predict there will be no errors or warnings and
disable all output prior to even having parsed the scene?  Sure.

GeForce 4 Fx :) This is *very* fast card. Ofcourse with newest drivers etc.

But newbies to PovRay cant. Same thing as with Sound settings (greate job 
btw).

*TWO* render buttons.
Or even better three,
[Run preview]
[Run Normal]
[Run Finla]]


And in .ini files You could define i.e.

[run_preview]
-a -g -Ga

[run_normal]

[run_final]
+a0.03 +ar2 +am2


Ofcourse this is obvious for You, me, and other povray users.
But software designer realy should think as a normal-peopes, that dont have 
a clue what .ini file is, and want to faslty have choose quality/speed, 
without reading tons of help. No all pov-users are programmers You know :)

Did you actually think about the consequences of your suggestion?
Essentially when previewing a scene during development of said scene you
could not see any errors.  Nor could new users see it.  POV-Ray would just
stop!

It should be absolutely obvious that neither new users nor any user for that
matter should be offered a user interface that shows no information in the
event of errors or warnings.  If an advanced users really elects to not care
about any errors and warnings it might be acceptable.  However, for a
default configuration to just not show any problems at all is about as wrong
as user interface design can possibly be!

Well right. Maybe just remove statistics stream and fie output then (from 
preview mode)?

But generaly idea of easy accesible 3 rendre modes (3 buttons, maybe 3 
short cuts) is not so bad idea? it is uded in every other rendering 
software i.e. moray (wireframe / raytrace / etc)

And disable saving INI to RERUN/ because rotating rerun hisotre needs to 
open/read/write/close over 10 files. Some ini option for not writing rerun, 
and add this also to preview.

You can already disable individual streams.  Please refer to the user manual
for details.

Hmm, maybe what you are looking for is a command-line version of POV-Ray?  I
think there are some optimised command-line versions of POV-Ray 3.5 that run
on Windows available.  I suppose others here know the links and can help you
out, if not Google should provide links to them as well.

I know.
I suggest to add predefined .ini and bind it to a key and to button.

alt+1 or button GO(fast) = turned off most streams -f +sp32 +ep4
alt+2 or button GO
alt+3 or button GO(final) = +a0.03 +f

and maybe also

alt+4 .. alt+9 - will fastly select quickres.ini section [fast_4] .. 
[fast_9] and render it.

I know it is possible, but new-users might not.

Thanks, but that was not what I ment, sorry if I was unclear (bad english).

I ment to turn off writting /render/rerun

I disabel writting to /render/rerun (just by renaming this dir ro _retun)
and it gave grate boost in speed of post-render.

The delay between finishing render and possiblitity to contue editing 
(beta-4.win32) is now about 0.1 second (ewen with all streams on, comes out 
that streams was NOT the problem).

Wouldn't something like the 'drop-down on a button' things like some 
browsers have make more sense. Just click the button for normal behaviour 
or the little drop down arrow to get alternative behaviors. That way the 
option is there, but you don't need 2-3 extra buttons. And I tend to 
agree here. New users won't know how to set these things manually, and in 
the case of the re-run issue, you can't apparently even turn that off 
anyway, even though Rafal says it can drastically speed things up for 
those of us that *never* or rarely use it in the first place. Renaming 
the directory so that it simply fails in all cases isn't much of an 
option, since when you do need it, you have to rename the directory again 
to reenable it. :(
