Ok, you are saying a complete move of rudder.vaor should take 2-3 seconds. And that 190Ds we fly in WBs uses stabilizing fly-by-wire software?
I bet this 190D did not have those control issues.https://www.youtube.com/watch?v=DjS1eggipm8&t=10s
In real life, controls become heavier with speed and as they become so, they're travel is both more limited and slower.
What speeds are you flying at? Every airplane has a sweet spot. That said, the part that puzzles me is that you notice it after an update, which implies it was not an issue before. I wonder if something changed in your stick setup with the update? I know several times after an update, the game 'forgot' my settings and left with a default setting for stick sensitivity. One of the many things I learned from Juice is to set all my controls to 100% from zero deflection to full deflection. That requires a lighter touch- which I think you have- and if those stick sets are back to default everything will feel wonky in the way I think you are describing.
Other than that, I have no clue at all. Good puzzle.
