Yes, they are.

But it was a final render, not a simple test! :)
I have to say that with recursion_limit 1 things were a bit less slow, but
the unlit parts were completely black, so I had to raise it to 3.
Not to mention the fact that without the glass object the scene looked much
brighter (who knows why)...

What about rendering the scene without the glass, saving radiosity data, and
reloading them later with always_sample off and with the glass objects
included? Would it look good? I have to try.

Nope. The scattering with that iso was really slow and didn't look that
good. But with radiosity it looks good anyway.
