I wrote a simple and stupid mini-tool to test Godot 4's 3D performance of rendering shaded primitive faces, it was inspired by duane's bunny mark, which is for testing massive 2D sprites performance.
The idea is to render as many as models with a fixed perspective camera, you could adjust number of models displayed with 3 sliders: x, z and layers, the total number of models is x by y, and layers controls how many layers of x*y models are displayed.
All models are loaded into memory upon starting of the application, so it would take a while and a few Gigabytes of memory upon starting, so make sure you have enough free memory before running the project.
The code is pretty rushed and I am not very familiar with godot's rendering api, so feel free to point any coding stupidity out if you find I did anything wrong.
