i recently switched from eth_dcr to eth_sc and noticed my eth hashrate has dropped by about 1.5MH per card. is this normal for the switch? or is it likely that this loss can be re-gained with some tweaking?
That prolly come from default -dcri value
You can easily test it on your miner type "-" or "+" to adjust it.
Lower value on -dcri mean more power for eth.
