Optiminer ZCash v1.4.0 has just been released here ! Best results are on linux, maybe 10-15% higher for Polaris cards. Fastest ZEC miner out there, and the fee is already included in the speed, so what you see is what you get. No fancy controls like claymore, and no flashy colors – but – faster speeds. For example (on windows) We can get 375 sol/s on R9 390 1100/1500 and 205 sol/s R9 380. Only downside is you cannot connect to coinotron so far. Don’t forget to set –experimental kernel command, run the .bat file with –help to see all the options.
