I'm seeing some gains as well, but for some reason sgminer won't take the same commands in the .bat file that the previous version (linked in the first post of this thread) did.  I've never messed with sgminer before (only cgminer), but the previous version took all of my old cgminer commands.  It seems that this new version also does not display GPU temp info and will not let me use "--gpu-engine X" or "--gpu-memory Y" commands.
