### Remarks

Unity requests the amount of memory that the game will use. [Profiler.GetTotalReservedMemory](/engine/6000.7/script-reference/unityengine/profiling/profiler/gettotalreservedmemory.md) is the full amount that Unity currently has.  Part of this memory is used by the game using [Profiler.GetTotalAllocatedMemory](/engine/6000.7/script-reference/unityengine/profiling/profiler/gettotalallocatedmemory.md), and the remainer is stored and unused.
