I managed to run the 64k block example, i.e. 64 10x10x10 stacks at about 40 fps a little while back, before I included the joints and springs support in the solver, so I'm positive that number can be made to run smoothly in real-time if you're laser focused on rigid bodies and optimize the pipeline specifically for it. With everything enabled though, I think about 10k bodies is the reasonable limit on my M3 Max. I do want to attack performance next, since I was mainly focused on stability and good support for various modes of physical interactions.
