I have seen a small 1.5-2% speed improvement poolside over Claymore 11.0 on my Nvidia 1060 rig.  Thank you.

My RX-480 cards are also 2-5% faster but not enough improvement to keep them on Ethash.  Their MH/s output has dropped 33% in the last few months.  Flashed a few BIOs and tweeked with Afterburner.  Is there a magic bullet to regain old speeds to 480s or is this the new norm for ETH algo?
