I might be wrong, but doesn't SSE require you to explicitly use it in C/C++? Laying out your data as arrays and specifically calling the SIMD operations on them?

There’s absolutely nothing you can do in C that you can’t also do in assembly. Because assembly is just the bunch of bits that the compiler generates.

That said, you’d have to be insane to write a game featuring SIMD instructions these days in assembly.

Technically assembly is a human-readable, paper-thin abstraction of the machine code. It really only implements one additional feature over raw machine code and that's labels, which prevents you from having to rewrite jump and goto instructions EVERY TIME you refactor upstream code to have a different number of instructions.

So not strictly the bunch of bits. But very close to it.
