FYI, for those ramping up efforts on the Neoscrypt coins on Zergpool, a new Excavator was released a few days ago (1.4.2a). Speed improvements on Neoscrypt specifically are huge (i.e. 15% jump on hashrate for my 1070/1080Ti cards from 1.4.1a).
https://github.com/nicehash/excavator/releasesI dislike it wholeheartedly, and the speeds on 1080 Ti are pretty much same as hsrminer or latest KlausT. 1350 or so, hsrminer shows more (and mostly delivers).
I've benchmarked all three (KlausT 8.19/HSRMiner/Excavator 1.4.2a) over minimum 1 hour runs. KlausT is more reliable that HSRMiner for pool-reported hashrate, but a bit slower. HSRMiner looks good on console, but hashrate on pool is quite varied and starts to slide over time: this is well-known issue discussed on Palgin's page. Excavator is definitely the fastest, albeit the config file for it is clumsy and the console output is missing some detail; beggars can't be choosers, though.
Excavator 1.4.2a (neoscrypt) benchmarks [Win 10-x64, NVidia 390.65 drivers]:
1080Ti (+110 pwr, +125 cpu, +250 mem) gets 1.998 MH/s. Previous version (1.4.1a) got me 1.78 MH/s.
1070 (no OC) gets 1.128 MH/s.
Confirmed by 24 hour runs to get pool version of reported hashrates.
