This is a bit beyond me as I don’t do graphics, only compute. But I thought it might be an interesting pair of threads for some here - in particular @leman and @Andropov. The author goes over the best way to transfer data between the CPU and GPU for different graphics APIs, mostly Metal, Vulkan, and WebGL.

Sebastian posts good stuff, I follow him too :) Of course, this is only relevant for someone writing game engines that are supposed to run on a wide variety of platforms and hardware. But in these matters modern Metal is as easy as it gets, especially on Apple Silicon. It's just regular old shared memory IPC.
 
Thought this thread would also be of interest to the same folks as the OP:
