for B777-300ER, as far as i know.....heat fumes and contrails are back. The bump map for the GE engine has been adjusted (to make it more rounded). Bunch of painters out there need to re-work the engine texturing to take advantage of the version 1.0.1. If you download their work using ACE or flightsim.to, you can see that engine outer ring is not aligned with their work.
