Despite not knowing anything about your code base, I recommend giving pre-compiled headers a try. I am currently working on a game + custom engine that is around 1M lines of C++ code. Thanks to pre-compiled headers and forward declarations, I can compile all of it in under 20 seconds (full rebuild, optimizations enabled).
