As a hobbyist, shaders is up there as one of the most fun types of programming.. Low-level / relatively simple language, often tied to a satisfying visual result. Once it clicks, it's a cool paradigm to be working in, e.g. "I am coding from the perspective of a single pixel".

It’s interesting that this hasn’t been solved for pixel shaders. With HIP in the GPGPU world I’m able to set breakpoints in a GPU kernel and step through line by line. I can also add printf statements to output values to the console.

You can do all that with Vulkan and RenderDoc.
