Seasons Greetings to all!

I'm curious to know, after all of my years multiplayering, if there's a reason and/or a cure for the lack of animation and limited animation seen between player aircraft during a session? I have a few people I fly with and they are spread across North America. We have a select few aircraft we like to fly very much but have to ignore the funky animation issues and effects that are active when they are not suppose to be (ie: afterburner displayed 100% of the time). I've tried "enabling" all the multiplayer parameters in the fs9.cfg on all of our PCs with no change.

Thank you in advance for any insight to this mild irritation.
