This article from the main author of the API describes how the buffer cycling works: https://moonside.games/posts/sdl-gpu-concepts-cycling/

This rubs me the wrong way. Resource renaming is a high level concept, which was one of the features of OpenGL that all the modern APIs have successfully dropped. A modern low level GPU API should not do that.

It’s so convenient to have buffer renaming as an user of a graphics API. What’s not to like about it?
