Implemented dual mining (Ethash/Blake2s) for some AMD GPUs (RX580/570/560/480/470/460 and Vega). Use the new -dpool, -dwal, -dpass, -dworker, and -dcoin options to set the Blake2s pool. You can set the secondary coin mining intensity with the -sci option. For more information see the Readme.txt file. Note that the devfee when using dual mining is 0.9% on the ethash coin (there is no devfee on the secondary coin).

Dual mining not working
I try everything but Nada
Chances are its a driver conflict. I just recently went through the last 15 or so driver releases trying to get a vega 56 working, and I also used some drivers on 470's and 480. From driver to driver the dual mining quits working. like for me the newest beta driver doesnt dual mine but the current stable does. mess with different drivers to get the dual mining working
