I saw in the release notes for 2018.3 that Vulkan is supposed to be the default API that the editor uses now, but it still runs as GLCore4.5 on my machine. If I do a standalone build, run it, and look at the log, it's pretty clear that is running using Vulkan however. Am I missing something that might enable it? It's not that I have an issue with the GL renderer, I was mostly just curious why it wasn't working.
