Windows 11 Build 22000.282 (KB5006746) is now rolling out to
testers in the Beta and Release Preview Channel of the Insider
program and it finally fixes the
performance issues previously acknowledged by AMD.
Windows 11 is rolling out gradually and a lot of users have
already installed the new operating system, but some have
noticed a substantial drop in performance. According to reports
and AMD, a bug in Windows 11 could reduce the performance of
compatible AMD processors.
In fact, users could end up experiencing issues with their
regular apps when running Windows 10 on AMD hardware. If you
installed Windows 11 on an AMD system and noticed performance
issues or problems with your apps/games, a fix is now rolling
out via the Windows Update.
The patch is titled KB5006674 (x64-based Systems) and it is
downloaded automatically on Insider machines.
Build 22000.282, which is now available for testers of the
Insider Program, finally addresses compatibility issues with L3
caching, which affected the performance of some apps. In fact,
AMD claims that L3 cache latency could increase by nearly three
times if users installed Windows 11.
As a result, the performance of apps was affected by 3-5%,
while some games performance dropped by up to 15%, particularly
the games used for eSports. Apparently, the bug was severe
enough that Microsoft immediately implemented their own fixes.
With Windows 11 Build 22000.282, if you try to load apps or
games on AMD CPUs, Windows will not reduce the performance of
However, there’s a catch – unless you’re part of the beta
testing program – which gives you early access to Windows
Updates – then you may not get this fix until the end of the
month. That’s because the patch will be tested with Insiders
and it will be released to general consumers as an optional
update later this month.
This fix will also appear in November 2021’s Patch Tuesday.
Until then, you can downgrade to Windows 10, stop playing games
(bear with the performance issue) or simply wait for the
optional update, which will be released later this month.
Other bug fixes in Build 22000.282 for Windows 11
In addition to performance improvements, Microsoft has also
fixed an issue that prevents the new Start Menu from appearing
on Windows 11 when upgrading from Windows 10. A race condition
bug has been fixed where Windows startup might cause a Blue or
Black Screen of Death error.
Additionally, Microsoft has fixed a bug that causes a Blue
Screen of Death error on PCs using non-ASCII text in the
