It’s a physical simulation, yes. The cube does rotate but at this rate it’s extremely slow, as expected:
You can’t see the actual rotation of the mesh with a naked eye. If I give it a long enough arm, though, I can observe that instead. Here’s the captured “movement”:
At this rate we’re talking some substepping or loss of precision. So yes, it does accumulate values and no, it’s far from ideal.
If I remember correctly, we had access to substepping when this was still pure PhysX. Not anymore. Scrub through this:
See if you can find anything that could be adjusted. There’s a bunch of entries that look sus:
