I tried the newest version of SMOS and it seems to be working much better. My GTX 1070tis now get recognized by name, but I still have the issue of GPU0 running at about 80% or less than what it should be. I've tried switching PCI slots and miners, but the same issue occurs. I have an 8 gpu Rig with 6 1060s and 2 1070tis. I'm using the Asus expert mining board, and when testing in Windows everything works fine. So I don't think it's a hardware problem. Tested Equihash with both dstm and ewbf
