If you have samsung memory ethminer can do 200Mhs... but ppl think Claymore is god for ETH, but he does not care for Nvidia users at all if you are stupid to mine with slower software and pay fee he will not work on optimization!
Why would he, when ppl have no brain to decide for themselfs
So...not sure how you came to that conclusion. I'm sure Claymore wants to optimize the miner for any / all cards as much as possible. The more efficient the miner, the more shares / MH he's going to get from each person that uses his miner...
You sir, must not know how difficulty works.
