AVX2 version of Pawnocchio?

Post by Alibaba »

Hi,

there are many versions of Pawnocchio, but which one is the right one if I need the Windows AVX2 version?

On a side note..I find Pawnocchio (dev) crashes consistantly in the Fritz 21 GUI, but not Aquarium. Does anyone know how I go about contacting the author?

Within Fritz, I discovered that Pawnocchio crashes with increments in the decimal format e.g. 1 min + 0.6 seconds.
