If you have Ryzen and Windows 11 you are interested in installing this patch –

Since Windows 11 came out on October 5, several Ryzen users have reported performance problems, hence AMD has worked to fix it, so if you have Ryzen and Windows 11 you are interested in installing this patch.

Some users had reported that after installing Windows 11 they saw how the general performance was considerably reduced, something that Ryzen users did not like, at that time Microsoft decided to launch a patch to try to fix it but they did not find the key and with that new one. patch what they caused was to create a new problem, this time with the latencies of the processor caches.

In this way things got worse because now there were two problems to mitigate, however AMD was able to get to work and decided to launch a new patch that corrects the operation of the UEFI CPPC2. This allows Windows 11 to choose the fastest kernel for certain tasks and thus maximize previously lost performance.

So once you update, you will see that the problem of UEFI CPPC2 has been fixed by AMD. In addition, they have also fixed the L3 cache latency problems with the update Windows 11 KB5006746This way the two problems should disappear, but if someone is still with either of them, it is better to report both AMD and Windows to release a new patch.
