The latest Bminer 13.0.0 should be the preferred choice for a Nvidia GPU miners that are currently mining Grin as it offers the best performance at the moment compared to other available miners. However there are still some things that may need extra work such as full worker support for Sparkpool (one of the first and largest currently available for Grin mining). At the moment you can use Bminer with Sparkpool, but all your rigs will be under a single worker called “miner-rig-0” as the worker setting of the pool interfere with the settings for pool, username and password schema that Bminer uses. The extra performance of up to about 50-60% compared to other miners such as NBminer or GMiner and others is well worth it.
We remind you that that Bminer is a closed source Nvidia GPU miner available for Linux and Windows in the form of pre-compiled binaries and that there is a 2% development fee for Grin, Beam, Bytom (BTM), Equihash and Zhash coins, 0.65% for Ethash and 1.3% for dual mining Ethash and Blake.
