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 :

i 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
