That's very kind . In fact, I've gained so much useful information from the Octane forum throughout the years, that this was the minimum.

Thank you very much for your support .

Now I had some time and found the issue that causes this kind of specific error (GPU render slows down when Cinema 4D is inactive - not in focus). I write it down in case anyone experienced it:

A way whole day gone with this and finally got here. The issue exists with Huion Kamvas 22 as well. Sudden freezes on different projects and tabs, when opening the material editor, octane settings, sending into picture viewer etc. Also with different octane versions, like the latest 4 and the 2020 ...
