If your code needs comments, it's either because it's unnecessarily complex/convoluted, or because there's more thought in it (e.g. complex mathematic operations, or edge-cases etc.). Comments just often don't age well IME, and when people are "forced" to read the (hopefully readable) code, they will more likely understand what is really happening, and the relevant design decisions.

Yeah, another way I've heard it phrased is comments are for explaining why you did things a certain way, not for explaining what it's doing.

and if you need an unnecessarily complex code for performance sake?

There's a comment for you to explain the why.

Rule of thumb: code explains the how and what, comments explain the why.
