Undervolting NVIDIA GPU in 2024?

Hey everyone,

I am using an NVIDIA GPU under arch linux for gaming. The one reason that is holding me back from switching to linux for gaming entirely is the fact, that you can't really undervolt NVIDIA GPUs under linux like you can with MSI Afterburner on Windows.

At least that has been the case for the last couple of years.

Has anything changed at all--especially with the *slow* "opening" of some NVIDIA driver functions--as of recently?

Undervolting has a significant enough impact to my power usage (around 50W), that I really want to be able to do that under linux.

Thanks in advance!
