Testing ccminer Alexis mod, but it seems it doesn't like my 1080s :
- 1070s = 1300 kh/s
- 1080s = 600 kh/s
with ccminer Tpruvot 2.2.1 = almost 1200 kh/s per 1080 (1050kh/s per 1070)

Anyone has the same issue ?
I know 1080 is not the most efficient for neoscrypt, but still doesn't explain a such difference.
