Yeah, the motherboard came with 2 long antennas, They are spread so 1 faces left, 1 faces right, pointed upwards. My modem is probably about 2 feet away.
Wired is the way to go.
Both for your ethernet and your mouse.
I know people will say 'but it should just work'... and it should, but it doesn't. Sooner or later, WIFI will screw things up, will add latency, and it certainly adds a less stable connection than a cable ever will. Consider that the vast majority of things are wireless now, and we're stacking technologies to make it all work. Also, motherboard antennae tend to be... sub par. Even just because there is a dozen other things that need to be shielded away in there.
Cable everything, and you can always safely rule out this hard to grasp cause. I've not had a single wireless device that was 100% problem free over its lifetime. It goes for everything even peripherals, if not especially, because todays' PCs already carry ever increasing latencies, and anything you want in realtime out of the internet adds even more.
You're also cutting out some processing to be done, a cabled connection is 'simpler'.
And if your modem is in arms reach... why would you even want wireless?

OK, so I guess I need to read the whole thread

I'd refrain from buying more parts. Rather, scale back to bare necessity.
1. Fresh OS install (a clean one)
2. Install one or two applications that used to produce stutter. Install only ONE browser and use defaults.
3. Set monitor to native refresh/res, no VRR. MAKE SURE YOU DONT GET STUCK IN DCH DRIVERS through windows Store. (are you on W10 or 11?)
4. Test with minimal peripherals connected to USB: Mouse / KB. Plug both into the rear (usually top) USB 2.0 slots of the mobo. Connect nothing else except monitor. Testing = your normal usage, so browser tabs open, etc.
5. Test a game.
6. Activate VRR. Test again (given the infrequent nature, I'd give it a day or two for each step)
7. Add one peripheral like the headset. Again, test.
8. Keep building back up until you run into trouble. This includes any non-default settings for video or audio, usb, and connectivity. Consider each one a possible cause and test accordingly.

If you can't narrow it down like that I'd start looking at motherboard, but also and perhaps first storage. This begins with cabling. SATA cables can fail. Swap them around if you haven't got spares, especially the one connected to your OS drive. If storage access is unstable, these stutters and all associated issues are plausible. Been there, done that
