How do I support SSE 3, SSE4 and AVX in one application/bundle? Do I check at launch what options (processor) are supported and then run a specific application from within the bundle? Are there other options to accomplish this? And how can I check which option is supported? If I select SSE 4.2 on my mid 10 Mac Por the program runs a lot faster then when I select SSE 3, I want to offer the best and fastest for every user.
