So if you spend any time viewing / answering questions over on Stack Overflow under the C++ tag, you will quickly notice that just about everybody uses the boost library; some would even say that if you aren't using it, you're not writing "real' C++ (I disagree, but that's not the point).

But then there is the game industry, which is well known for using C++ and not using boost. I can't help but wonder why that is. I don't care to use boost because I write games (now) as a hobby, and part of that hobby is implementing what I need when I am able to and using off-the-shelf libraries when I can't. But that is just me.

Why don't game developers, in general, use the boost library? Is it performance or memory concerns? Style? Something Else?

I was about to ask this on stack overflow, but I figured the question is better asked here.

EDIT :

I realize I can't speak for all game programmers and I haven't seen all game projects, so I can't say game developers never use boost; this is simply my experience.

Allow me to edit my question to also ask, if you do use boost, why did you choose to use it?
