[Hardware] The fixes for the Windows 11 bugs that were hurting AMD Ryzen performance are now live

[[M]anuel]

Fixes went out today for two Ryzen-related Windows 11 problems.

 

 

Fixes for two Windows 11 performance issues discovered at the beginning of October are now available for download. The bugs hindered the performance of some Ryzen CPUs after upgrading to Windows 11. AMD just put up an update on its knowledge base blog, flagging both items as "issue solved; solution available." 

"As of October 21, 2021: Windows 11 update KB5006746 fully resolves the performance impact of Issue 1 described in this article," reads the blog post. "AMD Chipset Driver 3.10.08.506 fully resolves the performance impact of Issue 2 described in this article. AMD has verified that the performance and behavior of compatible AMD processors are working as intended on Windows 11 subsequent to the installation of these updates. AMD and Microsoft recommend that users promptly install this update on affected systems."

Issue 1 was a problem with the measured and functional L3 cache latency nearly tripling on certain apps and games (meaning that the CPU was accessing its memory way too slowly). Issue 2 was with AMD's "Preferred Core" feature not working correctly. Preferred Core allows users to assign apps to the fastest core on the chip manually.
