SubStepping and asset changes

Just curious, I understand how sub-stepping works.

What I don’t understand is why an angular motor of 400 on a body of 10kg changes DRASTICALLY when you enable/disable sub-stepping at default settings.

I’m really curious to hear from people who may have more physX experience if anyone’s out there.

The issue is not bad in my case. I only have a few assets to change - but if any time I change the values of the sub-step to fine tune a particular asset I end up having to change every other phat asset as well… I’ll literally go nuts before ever publishing …
