runway lights blurry

[James757]

White runway edge lights and white centerline lights
appear blurry and not well defined,halo around lights.
lights sharpen and halo diminishes as you get closer
to lights. Green taxiway lights are fine. Is this associated
with the 3D effect?

There's no associated 3d effect (the fps cost would be enormous), the lights are made with just textures and manually made mip.maps. Be sure you have the Anisotropic filter enabled at 16x on your video card control panel, because it affects how mip-maps looks.

If it's already enabled (if must be configured to Enhance the application setting), then what you are seeing is probably normal, but cannot say for sure without a screenshot.
