The Automatic Memory Manager keeps track of the Max Particles that were Active in a single frame over the last X seconds (call this number M). If the Max Number Of Particles is greater than M, the Automatic Memory Manager can de-allocate unused memory. The Seconds Max Number Of Particles Must Exist For Before Reducing Size tells how long M must be unchanged for before the Automatic Memory Manager can reduce the amount of allocated memory.
NOTE: This value must be greater than zero.
NOTE: Default value is 3.0.
