• I have a problem, I press my setting for my outside traffic to have heavy traffic. Apperently, it doesn't work. Can you help me and reply to tell how does this mod work?:steamsad: :steamfacepalm:

-Please update this for the Airport DLC, thank you :O)

I'm not sure the author is updated until now. Should we add Heavy traffic density as a feature in TMPE's settings?

Why would this feature cause low fps and even more traffic jams.
