That's probably true.
I just started a try myself, but can't judge for the mesh of course.

There are sometimes things that require waiting for a faster computer :-) Doing
this scene with media would definitely be interesting.  I did not use photons
very often but they would also be useful when adding a glass pane to the window.

I made the experience that combining isosurfaces with radiosity can be very
slow.  I would probably use less slow radiosity settings and fake some things
with additional light sources etc. instead.
