I need to come back to this topic. I run the latest version 1.4.15 on Windows 10/64 with all updates installed. I use WebDav as Dokany cannot sync with FreeFileSync (or the other way round).
Even if absolutely nothing is done by Cryptomator, it used around 50 (fifty!) % of all CPU on a high powered workstation with mighty processors.
What is happening? What can I do?
