The render texture memoryless mode property.
Use this property to set or return the render texture memoryless modes.
Memoryless render textures are temporarily stored in the on-tile memory when it is rendered. It does not get stored in CPU or GPU memory. This reduces memory usage of your app but note that you cannot read or write to these render textures.
On-tile memory is a high speed dedicated memory used by mobile GPUs when rendering.
Note that memoryless render textures are only supported on iOS/tvOS 10.0+ Metal and Vulkan. Render textures are read/write protected and stored in CPU or GPU memory on other platforms.
