I’m planning on writing a game with C++, and it will be extremely CPU-intensive (pathfinding,genetic algorithms, neural networks, …)
So I’ve been thinking about how to tackle this situation best so that it would run smoothly.

(let this top section of this question be side information, I don’t want it to restrict the main question, but it would be nice if you could give me side notes as well)

Is it worth it to learn how to work with ASM, so I can make ASM calls in C++,
can it give me a significant/notable performance advantage?

In what situations should I use it?

    Almost never:

    • You only want to be using it once you’ve profiled your C++ code and have identified a particular section as a bottleneck.
    • And even then, you only want to do it once you’ve exhausted all C++ optimization options.
    • And even then, you only want to be using ASM for tight, inner loops.
    • And even then, it takes quite a lot of effort and skill to beat a C++ compiler on a modern platform.
