once it hits a steady state. This information also has a fairly negligible
impact and thus is also highly recommended.
This flag works together with a PxCreatePhysics parameter,
trackOutstandingAllocations. Using both of them together allows users to have
an accurate view of the overall memory usage of the simulation at the cost of
a hashtable lookup per allocation/deallocation. Again, PhysX makes a best effort
attempt not to allocate or deallocate during simulation so this hashtable lookup
tends to have no effect past the first frame.
Sending memory information without tracking outstanding allocations means that
PVD will accurate information about the state of the memory system before the
actual connection happened.
