Seems no faster than 0.6 on Pitcairn and Tahiti.
PS : my rx470 is hashing at (not counting fee hash)
~170sols/s with 1.0.1
~160sols/s with 0.6.0
so, you hacked the fee, but getting less on Rx 470 than with fee or i did not get your post.
I got 168mh/s long term average on MSI RX 470 on 0.6.0
I second stability of 0.6.0 on RX 470 rig(s). No impetus for unstable 1.0.1
Stability is of utmost importance for me. I don't have time to check them every hour.
