I have uninstalled Orbx SoCal for performance issues, however I still get KLAS on a plateau. And when flying by, the terrain/autogen loads like it's trying to load 2 different sceneries and elevations. I'm running P3Dv4.4, UTX, GEP3D, Toposim Mesh. I downloaded and installed the latest KLAS installer.
Also, I noticed the Live Updater didn't work for me and a friend. It only updated to something like 2.0.1 where the downloaded file is like 2.0.5. The friend of mine said his didn't update KLAX to the latest. A little off topic but figured I'd throw that in too.
