New PC, Win 11 jerky/stuttery, games+benchmarks all good

[eddiew]

Hey folks,

Weird and minor annoyance; my new 7800X3D build is performing like a champ in games, but dragging a window around the desktop, especially between monitors, is a clunky experience that takes a second or so longer than it should and judders all the way. All drivers are up to date, Windows 11 is up to date. Given the specs it seems impossible that the PC is in any way struggling or that I should need to lower settings to make it work smoothly. I can run a Win 10 VM within this one and the window dragging within it is fine. It's really got to be a Windows 11 issue.

Just wondering if anyone has seen this before and might have some ideas on resolutions?

Possibly related, I find my USB headset (used only for voice comms) often develops a fizz/crackle that is immediately solved by disconnecting/reconnecting to the channel I'm talking in. Not sure if there might be some janky USB issue going on and the mouse is getting "crackling" when moving windows around and that's manifesting as jerky movement? I'm very confused because my other USB headset has no problems. Unless it's that one headset is dying and there's no connection to the window movement issue, which is possible.

Thanks in advance!

Have you checked what the refresh rate is set too in Windows?

System > Display > Advanced Display.

Make sure the refresh rate is set correctly under here.

Also, have you tested with just 1 monitor connected to see if you have the same issue?

Same issue with 1 monitor, sadly. Haven't checked refresh rate... will do so when I get home. All my screens are simple 60hz models though, I'd notice in gaming if they were doing less

How are they connected? via HDMI or DP?

Do you also have anything like MSI Afterburner launching at startup?

1 HDMI, 3 DP. This GPU used to be paired with an 8700K where it ran Win 10 with the same screens absolutely fine.

I am running Afterburner, actually. Found I could take a solid 80mv off my GPU's defaults without it ever becoming unstable, saves a ton of heat and noise

Might be worth closing down afterburner and see if helps at all.

Seen issues in the past with it running in the background

I'll give it a go, cheers.

Although I have also found some redditors complaining about lagginess in 22H2 regarding windows explorer and task manager. The latter being the thing I forgot to mention but which is definitely very laggy as well Maybe I will be lucky and 23H2 will finally do something about it.

bios upgrade? i had simlair and was agesisa fixes that fixed mine

That's interesting to know! I made sure I got the 1.3vcore fix installed as soon as it was available, but I haven't checked for a new one since.

Any way you can show how this looks at all?

Awkwardly, I cannot today... I rebooted (vs my usual overnight hibernate) and the issue has gone away. For now.

Confused. I have noticed that idle CPU usage has also dropped; yesterday Shell Infrastructure Host was eating about 10% all the time, today it's at 0%.

Probably recur, because it wasn't the first time (nor the first reboot) but I guess that is how to fix it. Annoying though. My old Win 10 build had nearly 100 days uptime at one point...
