I just bought this book thinking it would be good. It's not. It jumps all over the place you have to sort of piece together what's going on.
After some talking with Packt, we agreed on a 9 months writing time: a tight schedule, but we felt we could make it working together with Marco.
We succedeed, albeit not to the level we wanted, but it was a huge learning experience for both of us (I am pretty sure is the same for Marco).
I completed the 5 chapters and recently started the "GPU Driven Rendering" section after chapter 5. I've found vkguide.dev far more interesting than the book mentioned in the article, at least for my graphics experience level.
