impressive score with a Vishera, close to my Ryzen !

about the --variation, cryptolight v7 is for TurtleCoin as far as i know. Jce is optimized for it and uses half Large Pages to ensure contiguous memory.

So, on jce the equivalent is --variation 4
but if you mine turtlecoin, it should be automatic.

jce Dualshares on the way, it will be like the lowpower of stak, but not ready yet, i've to implement it in assembly, it takes some time.
so i expect jce not to be faster than stak with current version lacking dualshare.
