Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Unfortunately AMD cards suffer from a reset bug, still.
The reset bug being that you can pass through the card fine, once. But if you try to pass it through again (or the card experiences an issue and needs to reset), they get caught in some kind of bad state and won’t work until power is removed and restored. Which requires a reboot or a only slightly less disruptive dance with system power states.
For vega and 5000 series gpu’s, there’s https://github.com/gnif/vendor-reset
Incidentally, nvidia gpus are so good at resetting, they’ve probably done so without you noticing. If the screen ever goes black for a fraction of a second and returns in normal usage, it was probably because it reset itself.
The lower 6000 series lower than the 6800’s for example may or may not have the issue. It seems most “reference” cards are fine, but custom vendor cards often but not always have issues. My reference 6700 works fine, but a sapphire 6700 probably won’t.
And the 7000 series is also fucky in a new way somehow. Gnif knows far more about this than me, and has basically thrown up his hands at how AMD doesn’t care. He’s made occasional posts about it on https://forum.level1techs.com/
Gnif is also responsible for Looking glass: https://github.com/gnif/LookingGlass

Virtual Machine stinkyness
You could try LookingGlass. That may require two GPUs.

scrcpy 2.0 is released, with audio support!
It's a pair of apps, one runs on a Windows virtual machine, the other on the host OS, that uses shared memory to copy a passed-through GPUs frame buffer. Runs fast enough to get 4k/120fps very low latency, so if you have a spare GPU you can game on it in Windows, from a Linux desktop. https://github.com/gnif/LookingGlass

Can you make a passed through GPU display to a emulated display in virt-manager?
Check out https://github.com/gnif/LookingGlass if you can accept a separate window.

looking glass doesn't detect my mouse
then everything looks normal. It's all up to EGL though, as looking-glass really doesn't have any code that handles image scaling (see here).

The Death of the PCIe Expansion Card
https://github.com/Arc-Compute/LibVF.IO/tree/master/ plus https://github.com/gnif/LookingGlass works pretty well. If you use an Intel GPU, particularly one of their new Arc dedicated GPUs, it supports the functionality on the consumer grade hardware without any trickery and you just need Looking Glass to map the outputs.

Passing audio from 1 VM to another for final mixing?
I'd like to introduce you to Looking Glass as a much higher quality and lower latency alternative to NDI when you are trying to relay frames between virtual machines within the same computer. With a patched nvidia driver to enable nvfbc on the gaming VM there is almost zero performance penalty when capturing gameplay. It also has options for audio, which I don't use because they didn't exist when I was configuring my system. I have a similar use case (gaming and streaming) and hardware (5950X + two gpus). I am not using proxmox, however. My configuration using QEMU and libvirt has this XML:

Wayland vs. X – Overview
libei looks useful. But IDK why libei is necessary to run Barrier with Wayland?
For client systems, couldn't there just be a virtual /dev/inputXYZ that Barrier forwards events through
And for host systems, it looks like xev only logs input events when the window is focused.
Is xeyes still broken on Wayland, and how to fix it so that it would work with Barrier?
With Barrier, when the mouse cursor reaches a screen boundary, the keyboard and mouse input are then passed to a different X session on another box until the cursor again crosses a screen boundary rule.
Barrier is a fork of Synergy's open core: https://github.com/debauchee/barrier

KVM Switch for Gaming and WFH
I have a similar gaming/WFH setup (2 monitors at 1440p 144hz) and I’ve been using Barrier instead of a physical kvm, and it works really well. Not sure if you’re open to a software kvm but if you are, I’m happy to answer any questions about it if you have any.

Autoswap Keyboard Layouts based on Operating System
Have you tried Barrier? I casually used it to swap between my main rig and my MBP. Took a minute to get it setup but once I sorted it all out it worked pretty well. It has some settings and tweaks built in to address some of the layout issues you mentioned...

IT/programming multi-monitor setup? (coming from 6x old 21" square)
Sorry, probably not entirely on topic and can't answer anything reliable about the multimonitor stuff, but a tip regarding the 2 mice and 2 keyboards for the 2 different computers: use this: https://github.com/debauchee/barrier It's oss multi-os software that lets you use one mouse and keyboard (server) on several PCs (clients) easily over your LAN.
