Cheers! Great work, atom.

You weren't kidding, WPA hashrate down 43% on my old GTX 700 series Kepler... Ah well, time to see what my 6700K can do...

EDIT: 6700K even worse - as expected. Maybe one day I'll buy a 10 series...

Try adding --opencl-vector-width 2 or --opencl-vector-width 4. Maybe it helps Smile

No difference, I'm afraid. I tried all sorts of combinations with --opencl-vector-width too with no success. Not stellar hashrates I know but here it is for reference. I'm not even cracking anything anyways...
