Yes, they will.

Of course it depends on your computer and image size.  If it isn't a 486
rendering 1024*768 it should not take that long.  You may want to tune your
settings and the scene should render is at most a few hours on any Pentium
class system.

It's a PII-392MHz ... The Output will be in 1024x768

I'll post the scene to pov.text.sc-f

I rendered it with "+SP16 +EP16" to get approximate the rendering time ...
This first pass took about 1 hour, so the final pass will take 16x16 times
as long
(256h) ~10days ... This approx. should be quite ok because I use no AA
(focal blur is on)

To have a smooth image in the far parts I need that much blur-samples and if
I lower the disp_nelems, the glass will get a redish touch ...

So I don't know where to tweak this anymore ...
