I wish he were more precise about how his optimizations speed things up.
What is it exactly that has changed? Are *all* renders now just magically
50% faster, or what?

No, not likely. Intersection testing will remain the same as well
as features such as media and radiosity. Complex textures and color
combinations will benefit as well as a possible speed up of multiple
colored light sources. Without having had a chance to test the
optimizations it is difficult to predict how much faster the "average"
scene file will be but you don't get something for nothing. For
example if you don't have a processor with 3DNow support you are out
of luck :)

Should there be significant improvement via his modifications to the source,
I would not hesistate to obtain one. :)
