Windows 11 has just reached many users, including those who have downloaded it for being in the Windows Insiders program, and who have downloaded it through an ISO image on a USB. There are already first experiences with Windows 11, and it seems that if you have an AMD CPU, you will notice a drop in performance in games until you receive some patches and drivers.
As seen, AMD processors that are officially compatible with Windows 11 show a three-fold increase in L3 cache latency with the new operating system. The new operating system has also been found to break the preferred core system in AMD processors (UEFI CPPC2), in which the two best CPU cores, which can maintain the highest boost frequencies, stand out in the operating system. , so most of the light traffic could be sent to them and therefore the cores destined for efficiency would not receive it.
Windows 11 does not start well with AMD CPUs
AMD and Microsoft have discovered this task handling issue and listed the potential impact on application performance. The higher latency of the L3 cache affects the performance of memory-sensitive applications, such as heavy applications or games.
With this discovery they noticed a loss of efficiency of between 10% and 15% in high-caliber games that make great use of the CPU. On the other hand, a malfunctioning preferred core system means poor performance on lightly threaded tasks. This occurs because the operating system does not know which are the two best processor cores.
All of these issues that have been listed in the Windows 11 release for AMD CPUs can be fixed through software updates. AMD is working with Microsoft to develop solutions for these problems through Windows Update, in an update that would be scheduled for October 2021 and that would improve the performance of Windows 11 in games.
