Hey Rigel,
T-Rex has a great option: "--keep-gpu-busy". Means, he continue the mining even with no internet connection.
Especially in the winter months that option keeps the GPUs warm and not freezing to death, it's a great safety feature just for the case. Is it possible to get that same option for your miner? Thats the only reason using T-Rex over Rigel.
(And maybe also add ProgPowZ to mine ZANO, would be awesome)
Thanks!
