I just rendered 2 blank scenes. One in Poser 12 and the other in Poser 13. Both scenes were identical and the render settings virtually the same.

This is the settings for poser 12

Above is the settings for Poser 13.

Here are the log render times for each

My graphics card is set to allow the program to control the outcome as to AntiAliasing and lighting and such.

My question is why does it take longer to render in 13, than in 12? In 12, it takes a quarter of the time to render the same scene. Thanks.
