Latest version of nicehash doesn't set P0

[poby]

Prior to ver 2.0.1.2 beta, nicehash sets P0 on starting up.  However after upgrading to the newest version (2.0.1.2 beta), there is no longer an administrator request to set P0 and hash rates are noticeably reduced.  Uninstalled and back to 2.0.1.1 beta and it works fine.  Has anyone else encountered this?
