Function set_performance_level

pub unsafe fn set_performance_level(
    callback: retro_environment_t,
    level: u8,
) -> bool
Expand description

Gives a hint to the frontend how demanding this implementation is on a system. E.g. reporting a level of 2 means this implementation should run decently on all frontends of level 2 and up.

It can be used by the frontend to potentially warn about too demanding implementations.

The levels are “floating”.

This function can be called on a per-game basis, as certain games an implementation can play might be particularly demanding.
