One build, and it is right on the machine in front of it
Handhelds and consoles run configurations that used to need a desktop, because the configuration is chosen for the machine actually running it rather than for the average one.
Shipping to hardware you have never seen usually ends in a settings menu — which is a way of asking the player to solve a problem they have no way to measure.
The alternative is an answer per machine, from what that machine reports about itself, at a cost small enough to pay every time. An answer that takes microseconds can be renewed continuously; one that takes milliseconds has to be made once at startup and then defended for the rest of the session.
That is the difference between a default that is right often enough to leave alone, and a menu that exists because the default was wrong.
We always publish a latency figure with the machine it was measured on. A microsecond number without its silicon is not a result.
