I don t know what the issue, but looks like Sedominer (and MVIs miner) can t handle more than
3-4 gpu (nvidia) in windows 10. CPU have the load 100% and miner reducing the hashrate very
significant - in 2-3 times.
In windows 7 all works well - as people in discord say.
For amd, Sedominer works flawless; but for nvidia - when we have pool now - cosmic miner, imho, much better.
