OpenGL & Vulkan are like Portal & Portal 2
OpenGL = Portal Vulkan = Portal 2
Both are made by the same people, have the same motivations, are made in the same language. Experiencing the former is a good experience. However, experiencing the latter is a whole other dimension of interesting. OpenGL is fun to learn, and Portal is fun to play. But I’ve decided to start using Vulkan, and god damn, there’s a lot. You have to enumerate through and interface with devices, you have to create debug messengers, validation layers, buffers, arrays, etc.. Portal 2 gave me that same feeling. (Spoilers for Portal 2): [Falling down into Test Shaft 09 was the moment I realized this game is a lot deeper than I thought. You have to manage repulsion and propulsion gels, tractor beams, faith plates, lasers, and more.] Once you use OpenGL/play Portal, you start to get good at it and can crank out a playthrough/project in a few hours. With Vulkan/Portal 2, it takes a hell of a lot more dedication, but by god its worth it.
