Ditto on holding off until 12 comes out. 11.3 doesn't have proper compatibility with the RTX series; it just recognizes it for functions sake. The 11.2 Poser didn't recognize the RTX cards at all, and the implementation is bare bones in 11.3. P-12 'SHOULD' have a more developed implementation. No idea how fine tuned things will be atm, but you may find the 2070 does a lot more of what you need in version 12.
