Is AVX used at all for NDI decoding?

Par : paulreimer
For dedicated NDI receiver PCs, I would like to make sure I am buying CPUs with the optimal feature set for NDI decoding, but I'd also like them to be as cheap as possible since I'll be using a lot of them.

So my question is:
Is x86 AVX acceleration used at all, for pure decoding applications? The monitor apps appear to work on older CPUs with only SSE3 support. (Some other NDI apps just crash immediately if AVX is not supported by the CPU).

When AVX is not available but an NDI app still runs, is it still decoding optimally? I don't want to leave any performance on the table, but I am also interested in pursuing the smallest/cheapest dedicated receiver PCs.
