Low FPS while using sight (VR)

[TheCrysinator]

Today was the first time I got back into the copilot seat since launch to try out the new ATGMs we got yesterday. First of all the current sight is a much needed visual improvement over the initial one but now I suffer from single digit FPS using it in VR. Because it's not flat and static like the last one it's also very shaky in VR. Is there something I can do from my end to fix/improve this?

For me its ok, max FPS as before (45).

I found that it has something to do with the zoom. Sometimes it's fine and sometimes it's a slideshow.
