Inquiry about mobile

Hi.. i'm working on racing type game... I just wanted to, well theres many tracks and for one of the levels I wanted to combine all the race tracks in the game to be in 1 single big "looping" track … my question is, will I have huge performance drops in mobile for doing this? the camera just renders where the player is currently at and not the whole level also!

 

You could use async scene loading to save on memory of having all those scenes loaded at once, and you could stream the world as the player travels around the tracks.
