Literally zero GPU usage and very low FPS?

[么嗷猫]

My game has only 1–10 fps in the title menu, and in the task manager, I can see only 0.1–1% GPU 3D usage.
I can play other games normally so I don't believe there is any hardware problem. My GPU is 3080 and CPU is 5950x.

The last time I played FO4 was in 2020, it was modded at that time.
I tried to start the game with F4SE and fallout4.exe directly, but no one worked.

Any clues?

Did you cap your fps using your video card suite? What is your monitor's resolution and refresh rate?

This is a common problem around here, I'd suggest using a google search since Steam's search feature is quite lacking, but there are likely other threads with other suggested courses, even recently.

Rename the Fallout4Prefs.ini to oldFallout4Prefs.ini
it's in Documents/My Games/Fallout4/ You can rename it back later if it doesn't help
Run Fallout Launcher and setup your settings.
Close the Launcher.
Reload it again and see it your setting stayed put.
Play... fingers crossed

I can't believe it worked... It had popped up once before when I tried to launch the game directly and it set the graphics level to Low because it couldn't recognize my graphics card. So at that time I set the resolution manually and enabled borderless window mode.

The truth is the game does not work in borderless windowed mode... so stupid

You can use Nvidia's GeForce Experience and let it optimise the game's settings for your GPU. Use the slider and move it all the way to quality. Your RTX 3080 should not have a problem with it.

If you want to tweak .ini settings can you use Bilago's Launcher - https://www.nexusmods.com/fallout4/mods/102 It is not a mod, but a free-standing tool that gives you a user interface for all the .ini parameters. On top of it can it work as a launcher for you and you can give it your own background and so have a personalised launcher with full access to all .ini file settings.
