Bug Poor performance out of the box

Hello everyone. I just picked up Unity and was looking for some starting template project to learn from. So I built the "2D Platformer Microgame" from the Unity hub, and the performance has been abysmal out of the box...

The game feels like it is running at 5 fps which can be clearly noticed from the parallax background movement (video clip: https://drive.google.com/file/d/1WFX23X9U9C0Mvftyxt1aLQH7lOj9qTbQ/view?usp=sharing).

I've read on another thread that Unity has performance issues when running in-editor. So I built a standalone version, and... honestly it ran better in-editor...

I am completely puzzled by this considering that I have a pretty good machine, and this game is drawing 10 sprites. The profiler is showing that the application is hardly doing any work as expected (image attached). I tried restarting my machine and running the build without any other app running side-by-side, but the outcome is always the same. My drivers are up to date.

My setup:

Unity 2021.3.26f1 LTS but also tried Unity 2022.3.0f1 LTS
Windows 11 Pro 22H2
CPU i9-12900K
GPU GTX 1070
32 GB RAM

Please help
