So is this better than Ewbf for Zec mining?
so far not quite. On 1080ti's I cant get better than 2.6%. power consumption is roughly the same. What bad is that miner is unstable and on nicehash pool creates a lot of rejected shares. I switched back to EWBF and 100% shares are good.
don't forget, that there is a dev fee integrated, while ewbf you can run without it
so that means - they are basically have same speed.
and if in your case nicehash have rejected some share from dstm - that's maybe some configuration errors?
