Instance Property


A Boolean value that determines whether the drawable’s textures are used only for rendering.


var framebufferOnly: Bool { get set }


If the value is true (the default), the underlying CAMetalLayer object allocates its textures with only the renderTarget usage flag. Core Animation can then optimize the textures for display purposes. However, you may not sample, read from, or write to those textures. If the value is false, you can sample or perform read/write operations on the textures, but at a cost to performance.
