The updated Gminer to version 1.49 proposes an increased hash rate on Equihash 150.5 (BEAM) and Equihash 125.4 (ZelHash) algorithms by 1-3%, but only for the latest generation of Nvidia RTX video cards. In addition to the already mentioned algorithms, Gminer supports 9 more, and for some of them mining is available for AMD and Nvidia simultaneously. Two versions of Windows and Linux are available for download, with a 2% commission. You can learn more about Gminer and the available hashrate on Bitcointalk.
