Thanks for the reply. About frame rate: its a 3d Godot and the gamedev is a bad programmer(it's me, i can't code to save my life). So I had to either remove second person view or separate the whole buildings in a separate loading screens to increase the productivity. But the whole point was to use the few viewports and because of that, i can't find a way to use a godot culling. I code myself into a corner, and the lack of playtesters is a standard for a jam situation.
