I have been playing ED for over a year now by opening the launcher, clicking on the ED Horizons 64bit link and then playing once it has all loaded. In that time I just minimised the launcher and played on the client like I would imagine most of you others?. Last night I upgraded my Comodo CIS security suite to the latest version 10 which is a whole new thing from previously and needed a clean install. This all went fine although time consuming as I couldn't import my old settings and had to reset everything including firewall rules etc etc. Today when I started up ED Horizons I noticed when reaching the opening screen that the bars in my power regulator were flickering as were a few other things. Thinking it was a problem with the new Comodo permissions I opened the GUI and saw that the Launcher was using 82% of my bandwidth while the Client only had 15%. My first thought was just to log out and restart but decided to close the Launcher first and see what would happen. Rightly or wrongly until now I believed that the Launcher needed to be open as well as the Client. Anyway after I closed the Launcher my game didn't crash and the Client bandwidth immediately rose to over 97% the power bars were now maxed and the flickering etc had gone. I then played ED Horizons uneventfully for a couple of hours until logging out. My question is this, does the Launcher need to be open while playing other than for starting the game and if it doesn't, then could the fact that it was using a lot of bandwidth on mine when I checked be responsible for some of these slow loading screens, server crashes etc etc that some of us have been experiencing ever since the v2.2 update?. Not sure if I have explained it very well but if not ask away.
