Godot: High RAM usage

[mastermarkus]

Godot version:

Godot 3.1.1 stable

OS/device including version:

Windows10 Pro 64bit
Intel HD graphics 4600

Issue description:

On Godot version 3.0.6 stable memory usage was around stable 200-250 but in 3.1 it spiked to 700MB and even higher, i also tested 3.1 alpha versions and it seems to be already happening in Godot 3.1 Alpha1.

Steps to reproduce:
Create empty project and open it up.
Seems to be system/hardware specific not reproducible on all systems.

Minimal reproduction project:
It's literally just empty project.

On my system with W10 and UHD 620 the maximum amount of RAM used by the editor is 430MB (with an empty project).
But even if it's more I would not consider it an issue. There are more features in 3.1 than in 3.0 so more RAM usage could be expected.
Also... people who want to make games should not do it on computers where Godot's RAM usage could be an issue. For their own sake. Maybe it could be good to add minimum/recommended hardware requirements of the editor somewhere on the website?

Most game devs i assume are gonna have computer past 2010 that has enough RAM and high enough OpenGL version to be okay. But still RAM usage seems way too high for whatever features were added in 3.1 Alpha1 and it hints something is wrong in the code.

When you know the editor usually only takes 130 Mb, 400 Mb more than necessary from 3.0.6 to 3.1 is NOT okay :D

Godot 4.0.dev.custom_build. d4b211bb3 on Ubuntu 19.10 with empty project(empty project.godot file) takes ~300MB.

I checked in Heaptack usage of memory

• 200MB - Editor - plugins, dialogs, editors etc.(Created inside EditorNode)
• 34MB - Shaders
• 35MB - RasterizerServer and DisplayServer
• 14MB - SceneTree(from SceneTree:init())
• 5MB - World3D
