@btw issue: What is your visualization method? For wire/solid bounding, full mesh, I can see the objects in the viewport, for point cloud I cannot - I reported that internally (Internal ID=631403480).
I'll let others talk about the performance thing.

What I mean: When I render them in IR they are visible as expected. But they disappear in final render.
See the right side is completely black, no proxies are rendered, they disappeared.
About the performance thing: Parsing time is now much shorter than yesterday. (less than 1min, compared to almost 9min yesterday) I'm not sure what the main reason for that is. Maybe computer restart, maybe some optimizations of the scene.
I also noticed that parsing time for IR is longer than for final render. Hope I can do some testing and give you some feedback.
