Adrian Courrèges is a software developer who, from time to time, does a break down on rendering techniques for major gaming titles. His latest one is on DOOM, and it explains, in remarkably simple (given the subject matter) terms, how the game draws a frame at a point early in the game. Most of the information was gathered from using debug tools, but a bit was pulled from Tiago Sousa and Jean Geffroy's slide deck at last month's SIGGRAPH conference.

I obviously cannot really summarize what the article says in this post. You kind-of need to read it for yourself. The post goes into how Vulkan is used for updating Mega-Textures, but it doesn't go into anything like asynchronous compute, though. Most of the figures are animated too, usually by a slideshow of images, but a few WebGL demonstrations are included, too.
