I have Orbx NA California but I am flying in LAX and have no 3d lights. My ftx night lights are selected. I have autogen to very dense and complexity dense. It's taking a big hit on my fps but I still see no lights. I'm at 4000 ft as well.

You need to move back up around Monterey before your Northern California (NCA) scenery will show. You still need to wait a while before you get to enjoy Southern California (SCA) scenery.
