I am running 4, 2pacs on NiceHash with your Windows build. My NiceHash reports say I am running at low efficiency as I am not using the #xnsub (extranonce.subscription ). I have tried adding #xnsub in the command, but it flags a URL error. My question is, have you incorporated the NiceHash include file for extranonce in your cgminer for windows builds? Thanks for all your support!
It's not and won't be. See the cgminer thread for details. Post there if you wish to discuss it.
