Turn off 3D models (or material shaders) lazy loading when playing a 3D game level

Hello, I was wondering, it it possible to somehow load all 3D models at once when loading the level? Now I’m facing the following problem: suppose the floor of the building with different 3D models around it (chairs, tables, etc). When I start our game and begin walking the level, there is constant FPS drops when I stumble upon some 3D model I have not seen before at this playthrough. When I already saw all these models, everything is OK. I think this is probably some kind of lazy loading, can I turn it off somehow?

P.S.: I asked this question on Godot discord, and the guys gave me the following issue link:

Compile shaders when a scene is loaded

This results in noticeable freezes in-game when some object is rendered for the first time. Behaviour that would make more sense is to compile the shader when a scene depending on it is loaded.

so this problem really exists.
Another advice was to preload my materials in a singleton on the start of the game.
But maybe someone has another interesting solution for this problem?

The singleton option is the best if your game is relatively small and doesn’t need too much RAM.

The other way would be to load models per scene, using Load() in a script and constructing the scene. But that would be for large games where you are already using chunks or zones.
