The latest CPUs support all the latest instruction set extensions- MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, FMA3, F16

Older CPUs might only support MMX, SSE, and SSE2.

These extensions improve performance for various things such as DSP and transcoding.

What extended Intel / AMD instructions does Mezzmo make use of, if any?
