I've been using Unity for the last 3 years and that book covers a good chunk of what it takes to make a performant game with it. Good books on Unity are hard to come by. Also highly recommend this book if you are just learning about game and simulation engines:

How is that 400 lines of code.
Or this one which even generates the sound on the GPU
With the wide adoption of WebGL, it's a good time to get involved in graphics. Furthermore, GPUs are taking over esp. with the advent of machine learning (nvidia stock grew ~3x, amd ~5x last year). The stuff nvidia has been recently doing is kinda crazy. I wouldn't be surprised if in 15 years, instead of AWS, we are using geforce cloud or smth, just because nvidia will have an easier time building a cloud offering than amazon will have building a gpu.
These are some good resources to get started with graphics/games
# WebGL Programming Guide: Interactive 3D Graphics Programming with WebGL
# Book of Shaders
# Game Programming Patterns
HN's own @munificent wrote a book discussing the most important design patterns in game design. Good book applicable beyond games.
# Game engine architecture
# Computer graphics: Principles and Practice
This is more of college textbook if you'd prefer that but the WebGL one is more accessible and less dry.
# Physically Based Rendering & Real-Time Rendering
These discuss some state of the art techniques in computer graphics. I'm not going to claim to have really read them but from what I've seen they are very solid.
Oh looks like there's a second edition coming out at some point http://www.amazon.com/dp/1466560010
