Before October 5th, 2022, only a few thousand people can upgrade to Windows 11 through the Windows Insider Program. After this time, hundreds of millions of PCs and laptops are eligible for the free upgrade from Windows 10.

Many uses can't wait to upgrade to experience the great improvements of Windows OS. But at the same time, the new operating system also exposes a series of problems, one of the severe known issues is that Windows 11 is causing performance problems on AMD Ryzen processors.

Windows 11 Performance Issues on AMD PCs

AMD and Microsoft jointly discovered that Windows 11 runs poorly on AMD processors, which have multiple performance degradation issues in Windows 11. AMD has identified two issues. The first is L3 cache latency increases significantly for some applications by as much as 3x, resulting in performance drops varying from 3-5% and even more in gaming. Besides, applications that are time-sensitive to memory subsystem access may be affected.

Another problem is the FOXI-CPPC2 (preferred core mechanism) may not preferentially schedule threads on a processor's fastest core. And programs that are sensitive to the performance of one or a few CPU threads may exhibit performance degradation.

AMD and Microsoft are working together to address these issues with the upcoming operating system and software updates. Microsoft released the first cumulative update to its Windows 11 operating system on Oct. 12 but seems to make L3 cache latency worse. This issue will be fixed via Windows update and the rollout is scheduled for October 19.

While the patch for the Preferred Cores (UEFI-CPPC2) bug will be released in an AMD driver update on October 21, 2022, according to an AMD statement on Reddit.  

Windows 11 Gaming Performance

As we mentioned earlier, Windows 11 update is currently making AMD performance slower, which can be reduced by 3-5% in affected applications, and higher in some games. For games, typically applications used in eSports, the performance drop could be between 10-15%.

For game players who have an AMD Ryzen-based PC, you can hold off installing Windows 11 until the issue is fixed.

Should I Upgrade to Windows 11

Windows 11 and Windows 10 share the same core features, but with some design changes in the interface. There have been no reports of major bugs on Intel-based or ARM-based devices, other than affecting the performance of computers running AMD processors.

Usually, the new version has the following advantages:

  • More powerful comprehensive performance
  • Higher support for new software and hardware
  • More user-friendly interface
  • Better compatibility, more stable operation

So, when a new version of Windows is released, it's in your best interest to upgrade your operating system to the latest version. New releases, however, tend to be unstable. So, you can wait a little longer for Microsoft to work out the stability and compatibility issues of the new software before upgrading to Windows 11.

If you are upgrading from Windows 10, Microsoft recommends that you wait until you are notified through Windows Update that the upgrade is ready for your PC.
