The latest GMiner version 1.33 comes with added AMD support for BEAM mining (currently only under Windows) as well as improved performance for Grin29/Aeternity and fixes. In fact this is a fixed release of the GMiner 1.32 release that was quickly recalled because of issues with GRIN soon after it was made available, the 1.33 seem to work fine for the moment. The performance you can expect from the miner for BEAM (Equihash 150,5 algorithm) is very close to what lolMiner 0.7 alpha5 manages to deliver and both miners do seem to work fine regarding NieHash support. Cuckatoo 31 performance for Grin mining is still slower (almost double) than what the latest Bminer 15.0 provides, though GMiner is more stable.
The GMiner Nvidia CUDA miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support. Do note that GMiner is a closed source miner for Nvidia GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.
