Fresh sgminer binaries with optimized Lyra2RE algorithm (by djm34) and support for multi-algo are available: https://www.nicehash.com/index.jsp?p=software#sgminer (thanks badman74 for windows build). Do not forget to include ";f9=1.5" to the password parameter of your NiceHash multi-algo configuration if you want to enable Lyra2RE for multi-algo.
