Anyone tried the new "improved" Cryptonight versions at all?... Or is it just still not worth the effort on nvidia cards? I'm still hoping for a miracle I suppose! 
On my 1070ti I gained from 1kh/s to 1.3 kh/s on Masari and on my P106-100 cards it went from 700h/s to 1.1kh/s.
So yeah, it seems to be a very nice boost!
