tried this with gminer 2.74 and later 2.66 as per recommendation by sp on flexpool. the hashrate unlock is not as good compared to trex or nbminer. will try tbm next weekend if i find the time.
Did you compare Gminer 2.66 with Gminer 2.94? GMiner already have a 100% unlock option, so using this tool with it will be pointless.
but..
2.66 0.65% fee
2.94 1% fee
