Until uploads are back on these are the cfg changes I made from the AI version. I don't know if they would fit in with the payware one. I had to assume all parameters were fair game to get the result I wanted so some values may seem out-of-whack but they work. Make a copy of your cfg then carefully copy and paste over the sections below exactly where they belong. Some sections are partial.
