You can take a look at this discussion[0] where Casey Muratori designed something like that where communication is done by opcodes, and packets instead of vtables. Note: search for "raw_device_operation" if you want to get to the code, but reading the whole thing is very worth it. [0] https://github.com/cmuratori/misc/blob/main/cleancodeqa-2.md

Pipelines (or in general terms PSOs) are the most problematic aspect of Vulkan / DX12 - much more than synchronization! Large parts of the gamedev industry seems to recognize all the performance issues with pipelines and therefore companies are experimenting with newer models like the VK_EXT_shader_object extension ("Vulkan without Pipelines": https://www.khronos.org/blog/you-can-use-vulkan-without-pipe...). I've written a detailed comment about this before here (https://news.ycombinator.com/item?id=37843946#37845431) but for a much more comprehensive explanation by an engineer from Nintendo read the initial proposal for the VK_EXT_shader_object extension: https://github.com/KhronosGroup/Vulkan-Docs/blob/main/propos...). And the slightly less-official behind-the-scenes tweet thread about the background for VK_EXT_shader_object: https://tw
