You didn't give us the Ground materials we can't view the ground without them you only gave us the setup layer.
Anyway I get maximum FPS.
And you have 3 dominant directional lights for what reason? You should only have one there is no reason to have 3 that is one major reason why it screws up in FPS.

i found the problem it was the grass and tree shadows i changed the grass model to the low poly one but still getting 30/28 fps and in oter computers should run worst anyway now i need to find a way to make a tree dont cast shadow if the player is too far
