How do I...?

Hi!
I am working on my game over months. On my desktop, FPS reach 144, but on other devices it is 20 (minimum FPS, that I set). I don’t know how to fix the problem.

I am using Windows 11, 144hz monitor.
Graphics card: NVIDIA GeForce 1080

Link to my game: Liluo game build

Hmmmm not sure what is up, I got 75FPS, Quadro RTX 4000, Xeon E5 2690v2, so not the newest hardware (nor OS) Played just fine for me.
