3 weeks ago Hi there, thanks for the report!
GNOME no longer shows an option to enable 240Hz output.
What does "no longer" mean in this context? Did it work before? What changed? Driver version, kernel version? Do you know what the last working configuration was?

3 weeks ago I did a little bit of experiment and it turns out that NVreg_RegistryDwords="RMForcePstate=0" was the root cause. But according to this documentation, P0 should be "best performance", right?

3 weeks ago P0 is maximum performance, yes. However, please note that the parameter above is not meant for end user use. It is an internal, test only knob that was never meant to be exposed (albeit trivial to discover by analyzing the driver; it's also not meant to be hidden). I can think of several reasons why it might mess with Is Mode Possible checks.
I really can't recommend using these RegistryDwords knobs (especially the undocumented ones) for anything other than temporary tests. We don't QA systems with these set, so you'll likely be hitting more issues where it's unclear what the root cause is.

3 weeks ago That’s true, but open drivers currently have stuttering issues after idle. I’m looking for ways to mitigate it.
