Getting the following error when running dforce simulation using the studio drivers,as well as the latest gaming drivers. Also tried different clothing just in case, and tried with a basic genesis 8, 8.1 with several different clothes, nothing worked, same error appears in logs over and over.

In addition, I did a clean NVidia driver install. All works fine when using CPU for simulation.

Most likely this is an issue with the curent nVidia drivers, you need to go back to a slightly older version (517.40 works) until their change log shows they have fixed the issue.
Question how do we roll back Nvidia drivers? I'm new to this card & don't know how to do this.
I figured it out :)
Yeah, I'll just use CPU for now, don't have a lot to simulate, but thought I rase the issue. Another thing I see is that IRAY renderer is falling back to CPU a lot, so I'm guessing tons of non supported issues there as well
