But that's the POINT!
This is not a decision that anybody can do for the user. The user has to
make this decision himself. Not the library, not the game that was written
before such capabilities were common. Only the user, who can judge whether
the machine has headroom enough that he wants the better performance.

Which is why you'd want per-program (or per-process) knobs to tune the
behaviour.
Something like environment variables, in short. Not global config files.
Not static choices by the libraries.
