Check it out at the DAZ Forums.
They talk about better Open GL too:
*"The OpenGL is vastly improved in both speed and quality in
C6. This allow for real time preview of animation while working with
content such as Victoria 4 etc.
Say good bye to very slow preview and jumping texture maps and hello to one of the best OpenGL views out there.
I am finding it to be a joy in using morphs and other character animation releated tasks in Carrara 6.
Some screen captures of the OpenGL coming soon."

*I don't remember ever being THIS excited about a software release...at least since Halo 2.
