Zoom does have a reasonable cutoff: there are combinations of older processors and GPUs where Zoom won't do background processing, but it's a far more appropriate cutoff that doesn't unnecessarily exclude very capable CPUs.

The proof is in the pudding: Zoom flawlessly runs background (video-based, even) processing on the same CPU that Teams refuses to do background processing at all (even where they used to do blurring), with no major stress on the processor. AVX2 introduced 256 bit integers and added FMA (more efficient floating-point operations), so I'm sure that made it somewhat easier to code some of the operations, but it's absolutely not a technical 's a decision to orphan somewhat older processors that are still extremely capable for background processing.

The fact that Zoom and other similar products easily do background processing on AVX1 processors shows that AVX2 is not 's just a decision that the Teams development group have made to not have to code to two versions of the AVX CPU instruction set extensions.
