Hi there guys
I tried myself to get smoothness at 100%.
FOV at 0.5 (it's the lowest setting I've reached with my mouse).
FOV Type: Dynamic.
Smooth type: Legit
Aim type: Non-sticky
Aside from the fact that I think that FOV Dynamic type has some really legit applications, I believe that the field of view itself is way too high, I mean. I've kept it tracked with the visual FOV circle and it's incredibly high, even a 0.5 makes some really unrealistic shots.
I'd suggest you guys make FOV a bit more closed for it to look more legit with the use of Dynamic FOV type. :)
