we are starting to compare apples to oranges here, but anyway I never was able to get higher hashrate on neoscrypt with Excavator. I gave it try again today, default settings benchmark from NiceHash miner 2.0.1.10 for single MSI GTX Gaming X 1070 pl90%/+100core/+400mem - result is 1241 kh/s. If I manually run Excavator from cuda91 folder - it gives more, about 1276 kh/s. But it is still way behind Nsrminer_neoscrypt_fork (even normal priority version) - 1322 kh/s.

You can see full hashrate compare of ccminer klaust, excavator and hsrminer_neoscrypt_fork at the 1st msg in my topic under Hashrate compare tag.
