I wish it was possible to put an argument to decide what time the next card will start.
Example: --gpu-init-mode 60, it would be for GPU 1 to start 60 seconds after GPU 0 and so on.
It would help in my region not to pay an energy tariff when the miner is initiated by the high demand requested in the network. With the non-peak because they would start separately, in the current one it still generates the tariff.
About DEV FREE, I'll get another log and check again, if I find any discrepancies I'll post it here for you to look at too, thanks for the clarification.
