Scene editor performance fix for scene with a lot of 3D instances (culling)

[StefanoGaming]

I noticed while working on a big open world type game that the large amount of objects in my map severely lags the project editor when I am trying to pan my camera or zoom in/out. However, when I preview the game the lag is not an issue since I have events set up to hide objects that are over a certain distance from the player.

My suggestion is to possibly add an option or just make objects by default unrendered/hidden while off screen in the editor.

I feel like this would be a simple yet effective way to boost performance in the project editor for bigger games.
