Unity provides a list of useful articles and tutorials containing VR design and optimization tips, which will likely get updated as the medium and market matures and new techniques are discovered. This list can be kept more up to date than this book ever could be, so check them out from time to time to catch the latest tips. As usual, the articles and tutorials in question can be found at https://learn.unity.com.

We should also keep an eye on Unity blogs to make sure that we don't miss anything important with regard to XR API changes, performance enhancements, and performance suggestions.
