Fix for Windows 11's AMD Ryzen L3 cache issue arrives in beta

[Corky34]

Looking forward to the AMD patches later this week but, in the meantime, W11 is working well IMO. I can still run Far Cry 6 and Flight Simulator with no issues. Really don't get all the negativity or people saying the launch has been a dog's dinner.

Considering the amount of bugs they've fixed in a recent Beta and Release Preview you're probably one of the fortunate ones, there's something like 60 of them.

I only installed it on the official release date, so maybe I missed most of those bugs?

Yeah, backhanders are almost certainly involved. There's no way you redo the scheduling and genuinely forget to test common scenarios on what is currently the most popular family of desktop CPUs.

Never attribute to malice what can be attributed to stupidity. Some middle manager who's probably of the age when Intel was all that mattered probably checked the charts and saw Intel still has most of the existing market (this is changing with new machines) so targeted Intel first. I've got the same problem at work. They want to shift me from a desktop to a laptop but so far keep offering Intel i7 machines that are slower than my i5-8500. Businesses have a funny way of sticking with what they know. It may also be naivety on AMD's part. Intel probably offered Microsoft some new engineering sample chips to play with, AMD didn't...

KB5006746 is now available via Windows Update for the L3 cache latency issue.

Also need to install AMD chipset driver 3.10.08.506 from AMD's site, which fixes "UEFI CPPC2 (“preferred core”) may not preferentially schedule threads on a processor’s fastest core."

EDIT: In case anyone else gets similar issues - when installing the AMD drivers, 2 of the 6 components failed to install. Guessing it's something to do with the upgrade to Win 11.

I had to use the MS uninstall troubleshooter util to uninstall all AMD chipset driver components (GPIO, SMBus, PCI, etc), then rebooted and ran the AMD driver installer again. This time all 6 components installed successfully. I verified each driver version in Device Manager too, just to be sure.

Heh, i just this morning reverted my PC back to windows 10

Why i was trying it is because theres a very annoying bug in win 10 that win 11 fixes
- If you have dual monitors with mixed cable types (DP and HDMI for me), if you leave the PC long enough to power off the displays, theres a roughly 80%+ chance of all desktop windows being shoved onto one screen when you wake it, meaning you have to manually drag all the windows back. Gets annoying very fast!

I too am familiar with this bug/feature and I agree it is annoying.
