Thanks tried it on my GTX 1070. Up to par with ethminer. speeds now
For dual mining I get quite some ETH hashrate drop for little DCR, so for now dual mining on my gtx 1070 is a no go.
well, dual-mining with gtx1070 still disappointed results ...
It depends on GPU, settings, selected coin, it's price and net diff. For example, for SIA on stock 1070 ccminer shows 1400MH/s. In dual mode in v9.7 I get 650MH/s SIA (so 45% of pure SIA speed) with only 2% ETH lost (about 25.8MH/s instead of 26.4MH/s).
DCR speed is not so good, agreed.
