I am truly puzzled by the total lack of interest in this remarkable development by Intel. This is a set of routines that, if implemented in Carrara, could boost its rendering speed by several orders of magnitude, while improving its rendering quality significantly.

Yet not the slightest interest, not even a 'Not bad, I'll think about it.' comment.

I am starting to believe that the problem with Carrara is not Daz, but Carrara users themselves, because they are not using Carrara in any serious project, therefore having a ten-fold or twenty-fold render speed improvement is of marginal interest to them

That may be the reason why Daz is ignoring Carrara. After all, if Carrara users don't care, then why should Daz?
