Synopsis

Description

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:

· "all"

· "altivec"

· "sse"

· "sse2"

· "sse3"

· "sse41"

· "sse42"

· "avx"

· "avx2"

· "avx512f"

· "arm-simd"

· "neon"

· "lsx"

· "lasx"

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

Availability

This hint is available since SDL 3.2.0.
