It should be emphasized at the outset that the problem described in this report is not related to the fact that Windows 11 security may reduce processor performance. The issue now concerns only AMD Ryzen processors and is due to the fact that Microsoft did not bring to the eleven even the optimizations that worked in Windows 10.
There are two major problems. The first is that the latency of the L3 cache in Windows 11 is for some reason 3 times higher than in Windows 10. This has a very negative effect on performance in latency-sensitive applications, especially in games where a ~ 15% drop in performance can be observed.
The second problem is the demolition of the system of preferred nuclei. In doing so, AMD ensures that the operating system does not shift the load between cores that are remote (higher latency) and that cores that handle the highest clock frequencies are used primarily. This also has a negative impact on games, but also on other applications, especially if they use a lower number of cores / threads.
Microsoft is expected to begin distributing a patch to resolve the issues through Windows Update in October.
