Vulkan

Vulkan is an open-source and cross-platform API (Application Programming Interface) available for Linux kernel-based, Android, and Microsoft Windows operating systems, providing high-efficiency access to modern GPUs (Graphical Processing Units) used in numerous devices.

Vulkan is a low-overhead 3D graphics API and it is better known among developers as the "next-gen OpenGL initiative." It has been derived from and built upon components of the Mantle API, which AMD donated to Khronos. Vulkan is said to become the replacement of DirectX and the most powerful graphics API ever made.
