In short: There’s a good reason Windows 11 is rolling out in stages – Microsoft’s new operating system still has a number of flaws that need to be addressed before it’s ready for widespread availability. For AMD users, Microsoft and AMD now have official fixes for a couple of known issues that were causing AMD processors to crash in release build.
Windows 11 is a tough start, but Microsoft and its hardware partners quickly worked to address some of the biggest build launch issues. For people with AMD-based systems, this included a bunch of bugs that resulted in up to 15 percent performance degradation for Ryzen processors in some esports games and 3-5 percent in some applications. The problem was further compounded by the first Patch Tuesday update, which only made things worse even when it fixed some of the known issues in the original version of Windows 11.

Last week, Microsoft began testing a fix for an issue that is causing increased L3 cache latency and slower copy performance. Official patch (KB 5006476) will soon begin rolling out to Windows 11 users, addressing this particular issue, as well as a number of others affecting sound, Bluetooth connections, app launch times, Windows search, and more.
The second issue was caused by a defect in the UEFI CPPC (Collaborative Power and Performance Control 2) driver, which is responsible for thread scheduling for the fastest processor core. This feature did not work as intended for processors with eight or more cores and TDP greater than 65W, which is why most gaming PCs with Ryzen processors suffered. AMD confirmed to TechSpot today that the patch is ready. accessible for all Windows users using Ryzen, Epyc, or Threadripper CPUs.
It’s worth noting that the issues are popping up as Intel prepares to launch its 12th Gen Alder Lake processors, with most leaks indicating that they will match or even outperform Ryzen 5000 series processors in terms of performance, albeit with higher power consumption. However, both AMD and Microsoft have kept their promise to deliver updates by the end of this month, which will make life easier for AMD users looking to upgrade to Windows 11, and especially those who have already made the leap.
