Hello Everyone! I apologize if this post isn't as organized as it should be.

Every now and then I try my hand at making a 3D terrain system for my game. It's typically a gdscript that reads coordinates in a json, dict, array, etc and then instances each point as a terrain node/tile (so I can dynamically change each tile). The primary issue I run into is lag with reading this data over and over causing lag and the many instances of nodes themselves potentially causing lag.

I have successfully implemented a render distance before, which I believe fixed the instance count (IRC works good for max 5k objects). The issue that I believe stopped me was the lag from looping over an extremely long dictionary every second (or less). The looping was so when the player moved, it rendered a new group of tiles based on the player location.

It took a long time to ask someone else for help with this because I didn't keep track of my small terrain test projects. I do not have any examples of what I'v

I want to make an FPS controller that feels realistic, like when you move you really feel that your character has mass. In Unity I would've done that with RigidBody, but how do I do that in Godot 4.3.1 with CharacterBody3D? I know that RigidBody3D is not suitable for character controllers. May anyone show me the direction in which I shall dig?
