Timescale for Vue to be fully working?

Can Bentley please confirm the expected timescale for the Vue engine to be fully functional? It's about a year or more since luxology was retired and it is still a struggle to produce images consistently with Vue.

the inability to produce ambient occlusion layers from Path Tracing, and issues with lack of control on reflections if they show, full layers not exporting correctly etc etc....

Previous versions of MS had so many bugs with parametrics that we cannot go back to older versions, yet the change to Vue is preventing us moving forward....
