Obviously you haven't seen my posts again and again, that you have to use the 64 bit background renderer on a 64 bit system to see render speed increases. I see about a 50-60% render speed increase here.

And while you might want a uber gamma correction tool, you don;t even have that built into the pro applications.. they all use photoshop as well for final image correction.

Quite a number of enhancements and bug fixes are also under poser pro's render hood.. improvements to displacement rendering, improvements on dynamic hair, and normal displacement rendering as well.

Way too many people take way too many things way too seriously.
