Will the new one be based on Vulcan or did you abandon that thought?

I am going to implement the architecture with the existing OpenGL rendering code and then see if MoltenVK supports everything we need.

The World::Render() function has been replaced with this. It just iterates through all modified objects, sends the data to the culling thread, and returns. So the entire time of rendering disappears from your game loop:

void World::Render(shared_ptr<Buffer> buffer)
{
	auto gfxdriver = GameEngine::GraphicsDriver();
	shared_ptr<SharedObject> o;
	gfxdriver->cullsyncmutex->Lock();
	gfxdriver->rendertarget = buffer;
	for (auto it = gfxdriver->modifiedobjects.begin(); it != gfxdriver->modifiedobjects.end(); ++it)
	{
		o = (*it).lock();
		if (o == nullptr) continue;
		o->Sync();
	}
	gfxdriver->cullsyncmutex->Unlock();
	gfxdriver->modifiedobjects.clear();
}
