Short answer it won’t work on a mac, but they actually have a directx/directcompute version of flex, which works on amd cards but windows only. Anyway the flexChop uses the cuda version of the library, not sure about Derivative’s upcoming official port (that one Nvidia Flex Build)
Curious why the derivative wiki says nvidia flow (https://docs.derivative.ca/index.php?title=Nvidia_Flow_TOP) is only nvidia gpus, where flow is actually directx only so should work on windows/amd unless it’s something specific to the implementation in TD.
They were targeting Unreal Engine for a while, which I guess is why they had directx versions, but anyway, they stopped updating all the gameworks stuff a while ago, including their unreal engine ports, it seems they’re only interested in raytracing and AI these days.
