Opengl is expensive to support, because drivers can be quite large today.

Vulkan lets dev do things directly.

You could say opengl is one "layer of crap" Carmack was talking about.

I'm still happy to use it though.

With Vulcan, you are more than ever as a indie developer faced with the question: Are you going to do a game or an engine.

You simply don't need to touch it.

Use the bgfx.

There are several wrappers for Vulkan that make it easier to work with, like V-EZ. Using one of the is probably the best approach for an indie dev.
