I recently changed the anisotropic filtering to  times 16 and FSX preformed well getting 25-30fps in the PMDG737NGX at FSdreamteam LAX. But when i flew past the airport the default scenery started twitching. It happens everywhere now and is very noticeable at big cities. My Specs are: 8GB of ram Processer: Intel Core i3-4130 CPU @3.40GHz and I use Windows 7 64Bit and I do not Have directx 10 preview on.

Yea I have seen this happen at many add-on airports. I figured it was something that happened to everyone so I never paid much attention to it. If there is something that could fix this that would be great. 

Most probably you've tried on DX9? You may be having addons that tweak scenery/ground imaging conflicting with one another. Assure you do not have two addons running tweaking the same entity.

Nope Just the airports

Yea I only notice the airports flickering as well. I am not using DX10.
