I'm still noticing a real difference in render time with objects in scenes, specifically internal grass clumps, since they were mentioned before. Using the micropolygon renderer is nearly twice as fast as the new ray traced objects option. Even with low AA settings. This seems to be contrary to the release notes.
Micropolygonal rendering seems to also look better, aswell. Ray tracing grassclumps seems to me like using very low quality settings in the old MP renderer. They are barely visible when raytraced. I'm confused.
I'll wait on more documentation on these settings, like Matt said was coming soon.
EDIT: Thanks for the clarification on which objects are ray traced, Matt. We posted at about the same time so I'd missed your last post.
P.S. I'm not complaining, not by any means, just confused. Thanks for the input and help.
