May you add "XMR Stack GPT" on the mining softwares too?
SGminer is tricky to setup. Don't think i can help. You didn't not name your cards and algo you try to miner.
XMR Stack GPU is in todo list, yes.
Thanks god. I tested HiveOS ccminer with crytonight, result is very disappointed compare with
xmr-stak under win10. I tried to compile xmr-stak myself but not success ..
Your comparison is not correct while you did with 2 different mining software on different OS! Also you can't add (or compile) new mining software on Hiveos or other OS like that. You can use only premade mining software on them.
