A variable that limits what CPU features are available.

Header File

Defined in <SDL3/SDL_hints.h>




By default, SDL marks all features the current CPU supports as available. This hint allows to limit these to a subset.

When the hint is unset, or empty, SDL will enable all detected CPU features.

The variable can be set to a comma separated list containing the following items:

The items can be prefixed by '+'/'-' to add/remove features.


This hint is available since SDL 3.0.0.
