I made a comparison between NBMiner and T-REX ERGO unlock, even though ERGO popularity is dwindling (which means more ERGO for us).
Cards tested:
RTX 3060 LHR V2
RTX 3060 TI LHR
RTX 3070 LHR
RTX 3080 TI
The results for the RTX 3070 LHR are very interesting, as there is around 18 MH/s difference.

What card do you have and what did you get in T-REX? Please include your Nvidia Driver version, as it does a difference
