Win11 KB5035853 Cumulative Update *may* cause stuttering and general performance problems.

[LabRat]

Just got done spending over 4 hours troubleshooting GPU, Power, fTPM, NVME HMB, etc.

I was having major stuttering in games like Avatar: Frontiers of Pandora, and HBS'BattleTech. 'thought it was a bad PCI-E 8-pin power cable (again) but, no.

So, After a bunch of (mostly pointless) troubleshooting, I uninstalled the Update that installed earlier today.
Suddenly 'all better'.

Another person w/ (suspecting) same issue:

Anyone noticing U41 FPS issues? Unstable frame rates? Stuttering? (Possibly due to Windows patch...)

FORUMS.ELDERSCROLLSONLINE.COM

Is anyone else experiencing stuttering or general instability in frame rates with Update 41?

My sys specs:

Can confirm I probably have the update (I install all updates blindly like a moron / since Windows won't let me avoid anyway).  Windows 11 Pro x64, fully up to date here.

 

Can also confirm, I've been having stuttering for a while now, since just after I tweaked and tuned my system.  I did updates too around the same time and the tuning showed all rock solid stable results.  I'm back to all stock now, and still stuttery.  Which was really weird for me because this new system was soooo buttery smooth when I first assembled and installed it, and also for a few days after I tweaked it.

 

Seriously debating on installing Linux at this point, but I REALLY don't want to deal with those headaches too. -_-

I'm only on Win11 because of my last GPU setup. 11 was the only reliable way to get AFMF from a 6500XT w/ rendering from a Vega.

I know I have a 'dirty install' @ this point and had intended to do a clean single-OS reinstall after my old new case comes in. 

If you need Windows-compatibility, I highly-recommend Win10 Ent IoT LTSC. -It's what I'll be going back to, now that I'm on a single-card (again).

Great shout. I have noticed some audio drop outs lately that could very well be due to this. Will take a look later and remove.

I was going to say I run windows 10 LTSC and it has been five years of seamless buttery smooth OS. Never had so much as a hiccup in games and I love that it allows me to control what windows updates the machine gets. Closest thing we have to a win 7 pro successor.

yeah, I had to back out of that as well; killed my mutli-monitor setup.

Well I checked, no such update is installed on my PC. Guess we are looking at a different issue!
