Khronos' Vulkan Guide
aims to give developers enough of an overview of the Vulkan spec to get them up and going. With links to further details, it also functions as quick reference for many of Vulkan's features.
Recently, they have updated their guide with a thorough list of all the new extensions
added in versions 1.1 and 1.2. Each extension is given a short explanation on why it was implemented and some of their potential use cases.
It's great to have resource like this that helps developers get into the Vulkan ecosystem as easily as possible. With so many Vulkan developers targeting Linux (according to LunarG's latest survey
), this should also help the game development ecosystem on Linux.
