well i made some more testing VS gminer 1.30 and f2pool gives quite big drop of hashrate using gminer with 28.1g/sec hashrate vs only 26.8g.sec actual hashrates that bminer 14.0 has, maybe it's because this setting:
Improved the miner fidelity by 8%-10%. You will not see big local difference but you will see roughly 10% higher speed on the pool side.
here's result :
https://i.imgur.com/WNwcjkd.pngi will test it further in longer periods, it's quite interesting result, if this fidelity option really works (i'm not quite sure yet whether gminer also has it or not) i will receive higher earnings than gminer with 28g/sec hashrate, with gminer there's no rejected shares, but teamviewer works slower with gminer, it also uses around 32gb pagefile
After mining GRIN for about 1 1/2 weeks with bminer, I've consistently had higher hashrates on F2pool than has been shown on the miner. I thought it might be an outlier *luck* result, but it has held true the whole time on both my 1080Rig (1080Ti x2 + 1080 x2) on GRIN-31 part of the time and GRIN-29 the rest of the time and on my P106Rig (P106-100 x6) on GRIN-29 the whole time. I've also seen that going from version 13.2 to 14.1 decreased rejects from ~1.8% to ~1.3% (again on F2pool). I've tried sparkpool and grinmint for a few days with different rigs and have had much poorer results, with sparkpool's reject rate hovering above 4.5% now (it was over 5% on v 13.2). Not sure what to make of all that except to keep using bminer on F2pool.
