More precisely, Eric Preisz and I wrote a book!
The book is called Video Game Optimization, and it covers everything you need to know to get maximum performance from any software project – but especially games. If you’re struggling with getting a great framerate out of your game, I highly recommend checking it out. 😉
Video Game Optimization goes all the way from high-level concepts like planning for performance in your project’s timeline, to determining which broad area of your system is a bottleneck, down to specific tips and tricks for optimizing for space, time, and interactivity. Based on the course that Eric Preisz taught at Full Sail University on optimization, it isn’t the only book you’d ever want to read on the subject, but we think it is a great introduction!
The journey from that initial conversation where our mutual friend Jay Moore introduced us and suggested I would be a good co-author, to the day when we finished and shipped the book was a long but rewarding trek. Eric moved across the country from Florida to Nevada, as he moved from teaching at Full Sail University to running the Tech and Tools group at InstantAction. He also became a father with the arrival of his son, Grant. I left after 5 years at GarageGames and helped build a new company, PushButton Labs.
A lot has changed while we wrote it, but it still felt really good to arrive at GDC, visit the book store outside the exhibition hall, and finding a big stack of Video Game Optimization sitting front and center. 🙂
