> FP64 is extremely slow on Nvidia and AMD GPU, thanks to market segmentation: full performance with FP64 is enabled only on “professional” cards like Quadro. So for consumer hardware, we implemented FP64 emulation using two FP32 numbers. Performance is still not great, but it’s much better than using hardware FP64.
