I find that alexis78 v1.0 miner gives a faster hash rate for LBRY than ccminer 2.1/2.2
Out of interest what hash rate's do you get with 5/6 1080ti's for LBRY?
5 gpu = around 2050-2100 Mh/s . But it`s damn hot + I use 3 founder edition gpu, which have dumb cooling system. With proper cooling my system would give standart 2300 Mh/s.
