I'd like to suggest a settings in regards to rendering the game. For context, I have an older pc, not exactly the best for rendering entire maps. So, maybe we can add a "Render distance" setting, with some fog to cover the non-rendered objects in a map.
Hi , fortunately there is already a render distance setting. Just open the World Editor [F11] and in the Scene Tree find a object called "theLevelInfo". Select it and in the Inspector pane you will see a setting called VisibleDistance. Lower the value to you needs (see pic). I hope this helps you and makes things playable with low end PCs. Since it isn't that beautiful there is no slider in the regular graphics settings menu, I think.
Thanks for the tip! Didn't know that existed, as I haven't been messing around with the world editor much.
