Landscape Plan For Flying Game

So I’ve got a flying game that I’m in the process of creating, and as one can imagine, assuming one sticks to the appropriate unit size (proper kilometers, no tiny planes), the landscape must be very large. However, world composition has the flaw that it is constantly loading and unloading with rapid movement, and therefore causes great lag. The landscape is just fine working on it’s own, but the issue is that the airplane gets too far away and despawns (size limits and what not). Now I could disable that, but if I do I am told there will be precision errors which sound problematic…

What should I do? Should I just scale everything down, readjust physics, and therefore make the map feel big? I need a very far “render distance” for the world composition to look right… All I really have is just a large island… World composition is mainly about optimization but in this case is useful for the purpose of origin shifting to avoid actor deletion or floating point errors…

I’m very interested in this topic, I’d love to know what you find out.
