Hello all, [firs post- don t bash]

I use the 3-led clip with PS3 eye and Opentrack, also only used this setup with Warthunder.
1. Is it possible to have zoom (fov change) when leaning into screen?
2. Moving around the cockpit is "jumpy" there are some certain spots were it jumps to what is looks like a predetermined position, is this normal?
3. Yaw - leaning head against the side sometimes does notwork.

Also if you have similar setup any advice is greatly appreciated.
A good day.
