Hi to all,
 I want to introduce my modified version of sgminer https://github.com/Enoch72/sgminer-MK/releases/latest
I found that this version performs exceptionally well using the new monero cryptonightv7 algo and a worksize of 4.
Using my old r9 390x card I found an hashrate of about 865 h/s , while Claymore performs 'only' 855.
Similar results using my HD 7950.
If someone can verify my claims on newer cards I will be grateful.
Results obtained using a worksize of 4 , 2 threads per GPU.
RawIntensity param values obtained using the formula : (GPU ComputeUnits-1) * 16.
OS Windows 7, AMD Adrenalin driver 18.5.2.

Hi, see you!
