Hey cwrmyy888 .
So I updated my drivers and ran a test on my dev machine again.
It seems with the latest drivers I get about 42 MH/s . I think I was using 13.12 when I was getting close to 50 MH/s .
So 44 MH/s on the latest drivers is actually quite good.
Thank you very much, I found the problem, the problem is the algorithm.good DEV
