The development for the WildRig Multi AMD GPU miner continues with the latest 0.12.9 Beta bringing some more performance improvements for various supported algorithms on the table. It fixes the hashrate drops observed with X22i and adds performance improvements for that algorithm up to about 10% compared tot he 0.12.8 release that also brought some speed improvements for all algorithms. There is also a slight boost in performance for the X16r, X16s and X17 algorithms in the latest update.
Do note that the WildRig Multi currently supports only AMD GPUs with the newer RX series and VEGA out of the box and there is a separate download of binary kernels needed for older R9 series Fiji, Hawaii and Tonga. Unlike its predecessor the WildRig Multi miner does not support Nvidia GPUs, it will only work on AMD-based mining rigs. The WildRig Multi 0.12.9 Beta is currently available for Windows, Ubuntu Linux and HiveOS as a closed source binary and with a 2% developer fee built-in by default, though it can be reduced.
