Hi Vlerkies,
Welcome to the Cliffs of Dover community!
To answer some of your questions:
#1: For me, the Team Fusion patch is the (only) way to go. Really amazing what Team Fusion was able to achieve. And there even will be a second patch being published beginning of September with a lot of additional changes...
#2: See the link already posted by bolox.
#5: Not sure if I got it correctly but the smooth zoom view that you saw in the videos might result from TrackIR.
For further questions it might be an idea to (also) post them in the
Team Fusion forum. There is a lot of active forum members there which are very much willing to help!
Hals- & Beinbruch und Horrido!
