I sort of suspected other people are having the same issue as I do. Few guys in my squad also complained about the same issue. Anyway ...
Unfortunately, the answer is no. FC 2.0 does not work the same way as BS. In BS it can be done and it works perfectly. In FC 2.0, once you set up your TIR for Zoom, your manual zoom in and out is then disabled. It works the same way as in FC 1.XX.
That's the difference between your and my set up. I use TiR 5 and it works like a charm. However, if server forces FOV then there it is a no go for me. Because I don't see important instruments in the cab.
First of all, with your video, you still needed to move your had down to see Beryoza, even with the "full zoom out" in the cab. I solved that problem with adjusting my Vertical Head position, see picture below:
Second, you dont use TiR for zoom. That tells it all. Without TIr for aoom, you can manualy zoom in and out. But, I can't with TIr.
You are not using TIr 3 for zoom do you?
