This problem has been annoying me for a extremely long amount of time now and I'd really like to know if there is a way to fix it. I have tried many driver versions with and without nHancer and no matter what combination of settings I use (trust me I've tried countless combinations in FS Settings/Driver Settings/nHancer) I cannot fix it. I took some screenshots to help me explain the issue to you.
Here is a side view of the SIA A380. No shimmer/jaggies edident on the textures.

As I pan around, the textures begin to shimmer.
