@Wolf0 and everyone else
Great work guys, I really thought the sgminer project was dead and I do remember Wolf saying it should be re-written from group-up (this was like 2 years ago).
We really need an open source miner like sgminer which can be easily adapted and modified with various kernels and features.
I tried the version you posted here and I got about 200 H/s from my 280X vs 295 HS/s with Claymore (Zcash) . Shame , I would have loved to use sgminer again, especially since I poked my nose in its original git as well.
