Earlier this week, Microsoft rolled out a Windows 11 patch that brough a fix to one of the two issues causing compatibility problems with AMD Ryzen processors. However, that release was only available in preview. Microsoft is now moving it to general availability.
Two problems have been causing compatibility issues between Windows 11 and AMD CPUs. The first Is found in the “preferred core” tech used in Ryzen chips. This feature is supposed to move threads to whatever is the fastest core on the CPU. However, it seems this is malfunctioning on Windows 11 and performance issues could be the result for some users.
It is this one that Microsoft is fixing with Window 11 build 22000.282, which is now available to all Windows 11 users. Unfortunately, this patch does not fix the second AMD-related issue in Windows 11.
That second problem stems from Windows 11 pushing the L3 cache latency to triple when running on Ryzen processors. AMD points out this would result in performance drops between 3 and 5 percent on applications, while games could see a drop of up to 15 percent.
Microsoft has not said when a fix this the L3 cache problem will come, but we presume it will be next week.
Windows 11 build 22000.282 also solves a few other problems on Windows 11. For example, some users were unable to open the Start menu after installing the platform. That issue has now been fixed.
Another fix solves input delays with Bluetooth keyboards and mice. And finally, Microsoft has also solved a weird bug that was causing some users to see the Windows 10 taskbar on Windows 11.
