After testing for many hours, i noticed a ~1% drop in hashrate for the lbry algo between 1.8.4 and 2.0, i tested various intensity settings for about 1h each, and overnight for the 2.0 with the same intensity as 1.8.4 (23.5), but i keep getting ~1730MH/s with 2.0 and 1745MH/s with 1.8.4, gonna try and test the 32bits version to see if anything change.
I used ver 1.8.2 64 bit is more faster than 1.8.4 64 bit.Dont forget there is gtx 1080 ti in presale which 30% faster then gtx 1080.
