I dont know about you guys, but now that i have tested these lights for a week or so, i have noticed that they are one of the most fps eating addon i've ever tried. Even with just the highway lights with 350m apart eats fps in cities like a horse.
It might get better if we could disable the actual 3d pylons, and have just the lights.
