I’m currently on Ubuntu 20.04.3 LTS and somehow my refresh rate is way off (close to 1000Hz). This directly results in not being able to run any frame-based experiments (each frame will just go super fast). My psychopy is 2022.1.1 I believe. My screen manager xrandr shows that my frame rate is 60 Hz…

Completely Wrong Refresh Rate on Ubuntu

Have you tried turning off “Sync to VBlank” in your NVIDIA settings app?
Take a look at this thread.

Cheers,
Flavio
