AMD and Microsoft release fixes for Ryzen slowdowns in Windows 11

Microsoft and AMD have both released patches to fix the AMD Ryzen performance bugs in early versions of Windows 11, according to an AMD Knowledge Base article updated late yesterday.

AMD has provided a new chipset driver to fix an issue that broke the “preferred core” feature that can improve performance on Ryzen processors with high core count and high TDP. Even if your system isn’t affected by this particular bug because you’re running Windows 10 or a Ryzen CPU with a lower core count, the new driver has fixes for a handful of other Ryzen and Threadripper systems running Windows 10 or Windows 11.

Another issue related to the L3 cache latency on all Ryzen processors, which resulted in a 3 to 5 percent drop in performance for most apps and up to 15 percent for some games. Microsoft started releasing a fix for the L3 cache issue to testers last week, and it’s one of many issues fixed in build 22000.282 of Windows 11 (you can see your build number by typing “winver” in a Run- window or Windows Search).

If you haven’t already installed the patch on your system, it will appear as an optional update in Windows Update for Windows 11 Home and Pro users, Microsoft says. Otherwise, the update should roll out automatically in the next Patch Tuesday package.
