Yeah, feels like controller axis dampening was reduced globally a couple of patches ago. I first noticed it flying the Mi-8, which was much more lively and sprightly after the change. It wasn't nearly as noticeable with the fixed-wing A/C, however.
But yeah, seems something has/was changed IMO too.
EDIT: And no, patching the sim did not change any of my A/C-specific preferences or flight modes, so it definitely wasn't that either.
