Sorry for the late reply, but I was kind of thinking of the same thing. Maybe they have it, but it just isn't on the beamng forums.
Here are 2 links I found though there may be more on the forums: - https://www.beamng.com/threads/simi...tracks-almost-daily.89133/page-6#post-1541212 - More detailed and better lighting but heavier on the CPU and GPU. I maxed at 60 FPS. - https://beamng.com/threads/nascar-tracks-thatonekidd789.86018/ - The track is less detailed but it's more FPS friendly. Maxed at 110 FPS.
