some of the new miners bundled with most recent version are screwing with the power limit set to 60% on my 1070, after a few hours I found that setting ignored and miner going on full power, any hint how to battle that horrendrous behavior, I can't pinpoint which miner does that because all work as expected with powerlimit 60%(set with afterburner upon boot in w10) until it goes wrong.
check if it's CryptoDredge, prior to 0.7.0, their DevFee sessions have (accused) been seen altering PL to 100%
0.7.0 and later doesn't do this anymore
