I have done some quick tests myself, not as valuable as testing in a real
scene, but it shows the effect in different situations:

Note that the times given are not extremely accurate.
It seems that in some situations differences in both quality and speed are
quite low, in other cases it's much faster without pretrace, but also much
lower quality.
What seems interesting to me is that in the first sequence (without light
sources) the 'medium settings' (last picture) give the best quality of all
the three cases.
