It would be great to hear a bit more about what we’re supposed to expect from Chaos at this point given it’s becoming the default. Simulating objects like my dice were wiggling all over the place initially and rarely ever sleeping on a static surface. That’s improved a fair bit now but anything stacking will never sleep still as of Preview 3. I haven’t tried Preview 4 yet. Groups of several hundred dice were going to sleep reliably in a few seconds with PhysX before.
