"i want archvis, terrain, and sss skinned people. sometimes together in one render. "

Then stop spending money on the poser application itself and
and invest in an alternative solution that will easily render poser content Like Vue  or the reality plugin for LUX

here are your archvis renders in Vue:

here are your poser people in vue

I probably dont need to show you any terrain samples

I have not upgraded from poser 6 because I use C4D and sometimes VUE /modo to render my poser content.
before that I used to import to bryce for rendering.

there are many options out there beyond waiting on an all in one solution from SM.
