It's silly to even start an engine in C++, as you need to be hell of a C++ programmer to even 'make' it to the same speed in nps as a much worse programmer can do in C.


I have to disagree. There is nothing magical going on in C++ classes if you refrain from using polymorphism. Last year I ported the low level parts of my engine from C to C++, introducing classes for Piece, Move, and Board, carefully watching for performance regression. There were none, until I replaced some low level macro's with inline functions. I accepted those as I wanted to get rid of the macro's. The performance dropped a small percentage (I don't remember what, but it was less than 5%). Probably even these could have been avoided by watching the generate assembly, I suspect there were some casting operations added under water.
