I tried with no skylight or shadows (it affects the temp-rendered mode) - makes no difference, still stays very slow.
You can try this one:
- the command is MultiViewCapture, but it represents general behavior of commands that come from compiled scripts - they all perform much slower in CommandLine refresh and interactivity than native Rhino commands while Cycles is running heavier scene.
Yes, it runs sequentially. If I set the sample count to 2 or 3, wouldn’t viewcaptured images only do the same ?
I may need to work on preparing some better samples for you to look at. Thanks!
