dForce freezing at "stabilizing simulation"

in Technical Help (nuts n bolts)

Hey all, I'm running DAZ 4.15.0.2 on my iMac (Catalina; 3.8 GHz 8-Core Intel Core i7; AMD Radeon Pro 5500 XT 8 GB; 72GB memory).

dForce USED to work just fine. But now dForce hangs forever. Just beachballs.

I don't know what changed to make it break but I would any help ya'll can give.

    First, what Engine are you using, CPU or GPU?  (under the advanced tab in dForce Panel)
    If you change dForce engine to the other, run dForce, then change back and run dForce, does it run on both,? It will usually recompile the dForce kernel when swapping engine, can be good too.

    Thanks for the reply!

    I'm using the CPU to render and if I try and switch to the GPU it says I need to compile the dForce kernels BUT it fails when I try to.

    CPU sims can be very slow, and someone else said before that dForce failed under 10.15 with the latest releases on an AMD card, I think it was the 5x series as well. I have AMD D700s in my macPro and there it works.
    CPU usually works (was a problem with Xeon processors in the early days of dForce)

    Hmm, so does this mean I just need to wait for DAZ to update and fix the problem? Or roll back to an earlier version?

    Really don't know as it did work for that person before, with the same DS version, so probabky an update from Apple for something that broke it.
