bool
true if the back buffer depth attachment can be memoryless.
A boolean property that indicates whether the platform supports memoryless storage for the back buffer depth attachment (true if supported, false if not supported).
Memoryless attachments live only in on-chip tile memory and are never written out to device memory, which saves both memory and bandwidth. This is supported with Metal on iOS, tvOS and visionOS.
This property reports only what the hardware and graphics API allow. Whether the back buffer depth attachment is actually memoryless additionally depends on the depth memoryless mode configured in Player Settings.
