- Microsoft makes update KB5006746 available in the stable channel of Windows 11.
- The update fixes a performance issue with AMD processors.
- AMD also publishes driver update 3.10.08.506 to fix second problems with its CPUs.
Microsoft and AMD are making available fixes for the performance issues that appeared with the initial release of Windows 11 affecting computers featuring AMD Ryzen processors.
Shortly after the release of Windows 11, Microsoft and AMD confirmed that the new version was causing compatibility issues that translated on up 15 percent of impacted performance on Ryzen processors.
Then the company made available a follow-up update to address the issues, among other problems, but the update made things even worse. However, days after, Microsoft rushed another cumulative update (KB5006746) as a preview for Insiders to fix the problem with AMD processors. The same update is now available as an optional update for the stable version of Windows 11, and anyone can download it from the Windows Update settings page.
At the same time, AMD is making available an update for its chipset driver (3.10.08.506) to address the remaining problem and, together with the Windows 11 update, put to rest the performance issues with AMD processors.
If you recently upgraded a computer with an AMD processor, installing both updates is recommended to make sure the performance is no longer impacted.
According to AMD, the driver update 3.10.08.506 “restores intended function and behavior of UEFI CPPC2 (“preferred core”) in Windows 11 build 22000.189 (or newer) on AMD processors. ” And, according to Microsoft, the update KB5006746 fixes “an L3 caching issue that might affect performance in some applications on devices that have AMD Ryzen processors after upgrading to Windows 11 (original release).”
You can download and install the latest update of Windows 11 from Settings > Windows Update > Advanced Options > Optional updates. It’s also possible to download and install the update manually from the Microsoft Update Catalog website. And, you can download the AMD chipset driver from this website.
