Back last week, we reported on a performance issue facing Windows 11 machines running some AMD Ryzen processors. The problem occurs in official AMD chipsets on the Zen+ and newer architecture. It now seems Microsoft and AMD will roll out patches to shore up the bug next week.
Both companies have been working on a fix. Last week, the duo said a fix would come “later this month”. While the official line has not changed, Wccftech reports it has information stating the patch will start rolling out next week.
There are two issues causing compatibility issues between Windows 11 and AMD CPUs.
Firstly, Windows 11 could be causing the L3 cache latency to triple. 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.
Secondly, Microsoft and AMD say there is also a problem on Windows 11 with 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.
Both companies have now addressed the issues with fixes. The report shows an AMD drivers power profile is in the release preview for a rollout on October 21. AMD says customers can ask for the update on request before this date.
As for the L3 cache issue, Microsoft has drafted a fix that will arrive with the 10C Windows Update on October 19.
Tip of the day: Windows Aero Shake is a handy feature that lets you quickly reduce screen clutter with a shake of an app’s title bar. Doing so minimizes all windows other than the one in focus, allowing you to focus solely on what’s at hand. Another wiggle lets you undo Aero Shake, maximizing the other Windows again so you can continue working.
Unfortunately, the feature can also have unintended consequences. Those who move their windows about or have dual monitors may notice that they’re accidentally activating Windows shaking. Luckily, enabling or disabling Aero shake isn’t too hard.
