Version 9.1 is definitely an improvement and it seems now that it is actually working as expected for me despite an old 3060 Ti card at least as long as I use the Nvidia 572.83-driver instead of the newer ones.
To the tread owner: Maybe you shall try the Studio-driver instead despite it might not be what you want to hear if you are a gamer too :-). Below you can read my experiences. This is just an initial test of some pictures but despite that I think version 9.1 is promising but the results needs to be verified or falsified with other pictures too.
New service release Photolab 9.1 - Issues? Solved any problems? - DxO PhotoLab - DxO Forum
What C1 has done is to invite the users to a lot of webinars:
and they have a lot of good educational videos too:
But I think it would have been really bad if something like the problems we have had with release 9 had happened with Capture One.
DXO has just chosen a different way . They still has an open forum but DXO doesn´t give it much love so here we just have to help ourselves and that doesn´t cost DXO all that much more than waht Caoture One spends on their users when it comes to a user dialog.
