Well, with a name like "Inside Direct3D" I was expecting an indepth look into Direct3D IM, but instead its a book about a game the author is programming. Unfortunately, rather than telling us how the game is developed, he's too busy trying to hide his programming secrets, and instead shows little snippets of code (with little explanation, and to be frank, obvious to any intermediate programmer) and then shows pictures of the finished product.
The optimisation section of the book, is again, obvious, and doesn't really go into enough depth (and doesnt mentions things like culling techniques or tree data structs).
Most of the information contained in this book can be extracted from the DX7 SDK, or from the web.
Makes a good doorstop... :o)
