This should help maintain Nvidia’s zero RPM mode
I hope this fixes my 7900xtx’s 100w idle power issue…
Have they? VRR support in Linux is still a total crapshoot in my experience. VRR doesn't work at all with multiple displays in X.
Which DE? I am using Plasma and notice some weird things like flickering screen when I am playing YouTube videos in Fullscreen with VRR.
X is legacy software that just needs to die.
And don't even get me started on the window and compositing manager with the same name.
Is this a joke? X can’t do VRR at all and I have yet to find a Wayland DE that doesn’t require a separate server pinned to each monitor. And neither support HDR.
Xorg works fine with VRR on a single display although no one should use Xorg, it's legacy software and no longer in development.
Wayland VRR works out of the box with most popular DEs like KDE or Gnome.
HDR can be added to gamescope, but be aware it's still considered experimental.
AMD experience was nothing but flawless, only Nvidia was buggy due to their drivers, but they're preparing Wayland support soon.

Neither KDE nor GNOME even detect either of my 144Hz panels as capable of it. Logs indicate that amdgpu failed to parse their EDIDs. Forcing the mode with a kernel command option causes link training to fail altogether. Meanwhile, the exact same system, panels, and cables running Windows works perfectly.

See above. I’ve also tried NVDIA and had the same experience - neither HDR high-refresh panel are usable in Linux, but both work on Windows.
Plus there’s the fact that about 50% of the time, when the panels power off from idle, they never come back on. This is apparently a known issue on AMD that’s been around for years but nobody seems to care to fix - everyone just says to disable screen blanking.
And don’t even get me started on heterogenous DPI.
I'd just like to interject for a moment. What you're refering to as Linux, is in fact, GNU/Linux, or as I've recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!
There is, for example Android, Google/Linux, or as I've recently started calling it, Google+Linux
Linux is an open source operating system based on UNIX. There are multiple different distributions (different versions developed by different people) which offer varying benefits. All distributions offer much more customization than windows, and some distributions have a similar GUI (graphical user interface) to windows, making the user experience very similar.
One of the biggest advantages to Linux is that Windows tracks user data, so users who care about privacy usually choose Linux.
Can't wait for this to be rolled out with bugs and spending 30 minutes tracking down the reg code to disable it.
I wonder if this actually fixes the ancient dwm bug that causes simultaneous motion on multiple monitors with different refresh rates to make the whole window manager choppy. That bug has existed since at least Vista, and it sucks. Nothing like buying a 240Hz monitor and not being able to watch videos on my secondary one without bringing them both down to what looks like 60.
Didn't even know this was a thing, and since I live by multiple monitors, this makes me glad I've held off.
On the topic of NV31 idle power: https://videocardz.com/newz/amd-radeon-rx-7900-xtx-idle-power-consumption-drops-from-104-to-20-watts-on-4k-144hz-monitor-once-vrr-is-enabled
Not much can be done about that. If you're not hitting a vertical blanking interval compatibility issue, you're likely hitting a bandwidth constraint requiring maximum mclk at idle to sustain those displays.
With that said, the idle power improvements have hit various display configurations, including many dual monitor setups.
