Currently mining 2.850 Mh/s with R9 390. Is there a better sgminer release or do I have to deal with it? I would also like to know how to run a full node, I'll put it up ASAP. This cryptocurrency seems promising and I'd like to support it.
Wolf0 has created a better miner for AMD. It goes like shit off a shovel. I don't know how much it costs though. I'd like a copy for myself.
EDIT: One day in the future I'd like for the best miners to be freely available. Its only fair that the devs who do the hard work creating new miners get some coins out of their efforts though.
There was a discussion about the miners few pages back:
