This is the enum used to determine how gameplay recording can occur, if at all.

Value Meaning
0 Disabled
1 Enabled
2 Automatic

When this value is 0, gameplay cannot be recorded. When this value is 1, the game must manually sacrifice some of its heap as transfer memory for AM's IApplicationProxy->InitializeGamePlayRecording(). When this value is 2, AM will call NS->BoostSystemMemoryResourceSize(), and allocate the required memory for recording automatically without the usermode process having to do anything.
