Not to throw a wrench in Miner Control, because I love this thing, but damn...
https://www.nicehash.com/index.jsp?p=news&id=47I had taken ffpool and hashpower out of my config. They were significantly under performing compared to nicehash, even tho they were reporting higher numbers at times. The more time I spent mining those pools, the less I was earning. So I was mining only on nicehash anyway.
I still use miner control on the few AMD cards I have left running.
