You should probably decrease 'adc_bailout', the suggested value is
'0.01 / brightest ambient object'

Is there any reason for this limitation BTW?

Not that *I* know of. I remember being pretty pissed when I found it.. I
was working on my own "light a room with only radiosity" project and I
just couldn't get rid of the artifacts.

Assuming he's using MegaPOV, I would actually suggest *increasing* it to
1. This is counterintuitive, but in my tests it seemed to give a small
speed boost without significantly affecting the image, whereas other
values had no useful effect.

As you replied to a comment on the first version (hmm, up to now I haven't
found out how to adress news articles as URLs...), you originally went for a
gloomy, oppressing Orwellian mood - so what about a televisor displaying the
latest news from the Malabar front, one of those famous "Big Brother is
watching you!" posters, a crumpled pack of Victory cigarettes (with the tobacco
crumbling out of the paper) and a newspeak dictionary on the table, not to
mention a more worn-out and shabby overall look of the scene?
Now, the room looks more to me like the dwelling of a daylight-dodging cranky
computer hermit...
See you in Khyberspace (under construction)!

I remember i once managed to reduce artefacts by decreasing it, not sure
if it works the same in this situation of course.

Hehe actually I just finished reading 1984 for the first time a few weeks
ago, so those image are fresh in my memory, however I don't think any of
that would fit with the alien in the alcove. I think the "dwelling of a
daylight-dodging cranky computer hermit" look you mensioned works better
here.

Thanks, I'll play with the adc_bailout a bit and see what I get.

The Party would never allow the books in the corner, the picture on the
wall, the calendar... ;)

The books definetly not but the rest ... perhaps if they were produced by
the party and prominently displayed political sayings and images.
