All the best, highest performance AAA games have been written in C++. So have all the slow, under-performing, crash prone, unoptimized AAA flops. C++ isn't a magic bullet that gives instant speed. Indeed a long running native app that isn't properly written, will fragment the heck out of memory and get slower and slower. (With 64bit address spaces, at least they don't crash now days!) The choice of algorithms and data structures is of utmost importance. Optimizing around one's run time is choice #2. C++ doesn't provide some magic hyper optimized environment. Heck C++ doesn't provide much of anything. You need to build a threading model and concurrency model that works, and performs well on different platforms. File I/O performance is different based on the file system in use, NTFS for example hates lots of small files, other file systems have less issues with that usage model. This goes on and on and on. With C++, every decision has to be made, and each one of those decisions can, if made incorrectly, lead to a poorly performing app.

A badly written C++ application will still be faster and consume less memory than anything written in JavaScript. C++ has a defined threading model and libraries since 2011.

  To be charitable, I'm gonna interpret this as hyperbole. If you meant this as its written, it'd be an immensly ignorant statement. Almost by definition, there CAN always be a faster implementation in C++ but there are also more ways to shoot yourself in the foot (or as they saying with C++ goes, shoot your leg off).

      Spoken like someone who has never seen obfuscated/underhanded code contests. C++ can do fuckery that rivals higher level languages just because of the limitless hardware access and undefined behavior the language has.
