I remade the same minecraft like game in OpenGL and Vulkan. Both versions rendering 64x64 chunks. (vulkan renders slightly more verticies than opengl because outer walls are also meshed). As you can see vulkan is pushing more frames than GL because of little cpu overhead. Instead of submitting each vertex one after another you can pass all draw commands with one submit command to the gpu. Both projects are completely coded in C. Vulkan utelizes my own allocator.
