Vulkan

Vulkan is a new platform-independent graphics API which is more verbose, explicit and designed to have low overhead . It is generally considered to be faster than other graphics APIs such as OpenGL, because Vulkan is new it is generally not supported on older systems. Vulkan is created by Khronos Group and is influenced by the Manite by AMD.

OpenGL vs Vulkan:
1. OpenGL has two APIs for mobile and desktop development, Vulkan has an unified API for both.
2. Precompiled shaders, OpenGL uses GLSL for shaders, which forces the OpenGL driver to implement a compiler for GLSL. Vulkan drivers only consumes pre-compiled shaders.
3. OpenGL has a single global state machine whilst Vulkan is object based and does not have a state machine.

1. Just recently started learning Vulkan.. phew, it's hard.
2. Stay strong! It is the future!

Person #1: What Graphics API are you using? DirectX or Vulkan?
Person #2: I'm using DirectX because I get better FPS
