Also we have been getting bigger hashrate for about 3-5% with lower settings on SMOS Linux 2.0 although with a different miner called DSTM.
Nothing to do with OS, its because of the miner. EWBF is old and not developed for a long time now. Where DSTM is in active development.
I tried SMOS 2.0, but way too many bugs, too fresh, I`ll wait few more releases then try again. They don`t even have option for sol/s for ZEC, but kh/s.
I cannot afford to be faffing around with SMOS spending my time making screenshots to devs of whats not working, I need to be mining to make money.
