The fix comes with AMD Ryzen Chipset Driver release iii.10.08.506.
Microsoft fixed a divide issue affecting AMD chips running Windows eleven earlier this week.

AMD released a chipset driver to address operation issues affecting PCs with AMD chips running Windows 11. The update fixes an issue that affects AMD's preferred cadre technology, which shifts threads to the fastest core on a processor. Affected PCs saw performance drops, causing frustration amid gamers. Microsoft likewise fixed a separate issue that affects AMD processors running Windows 11.

AMD outlines the fix for the consequence related to its preferred core engineering as well as Microsoft'due south before ready for the L3 caching result:

Known Functioning Changes	Impact	Resolution
Effect 1: Measured and functional L3 cache latency may increment for some applications.	◦ Applications sensitive to retentiveness subsystem access fourth dimension may be impacted. ◦ Estimated functioning impact of [less than] 3-5% in affected applications, with possible outliers in some games.	◦ A Windows 11 software update is now available to address this issue under Microsoft Knowledgebase ID 5006746. ◦ More information on downloading and installing this update can be obtained nether Microsoft commodity KB5006746. ◦ Systems with this update applied will enumerate KB5006746 in the Command Panel > Programs > Programs and Features > Installed Updates interface.
Upshot two: UEFI CPPC2 ("preferred core") may not preferentially schedule threads on a processor's fastest core.	◦ Applications sensitive to the performance of 1 or a few CPU threads may showroom reduced performance. ◦ Operation touch on may be more detectable in >viii-cadre processors above 65W TDP.	◦ An AMD Chipset Commuter package is now available to address this issue under version 3.10.08.506. ◦ Systems with this update practical volition written report AMD Chipset Software 3.x.08.506 (or newer) within the Apps & Features interface of Windows eleven. ◦ In add-on: ◦ For AMD processors with the "Zen 3" architecture: Systems configured with AMD Chipset Driver three.x.08.506 (or newer) should written report version seven.0.three.5 (or newer) for the AMD.Power.Processor.Settings entry in the Windows xi Provisioning Packages interface. ◦ For AMD processors with the "Zen+" or "Zen 2" architectures: Systems configured with AMD Chipset Driver 3.10.08.506 (or newer) should have the AMD Ryzen™ Balanced ability programme selected and active in the Control Panel > Power Options interface.
