I found out what caused the slow render times. It never dawned on me until I looked at the number of pixels selected. The lower the number the faster it renders but according to the Poser manual quality is not as good at lower pixels to sample. Here are some render times based on pixel sample size.

10 pixels - 9.13 sec             16 pixels -  24.82 sec         24 pixels - 52.54 sec   32 pixels -  90.26       The higher the pixel number the longer it takes. With Poser 12   I was using 128 pixels and .002 and it was fast compared to Poser 13 with the same settings which took six times longer.  Well, that solves the render time dilemma. The texture issue comes as warnings but the scene renders okay so I will ignore the warnings because it's too much work to edit older content. Still not going to buy P13 but that is my choice.
