AMD has confirmed that there are some performance issues under Windows 11 with different Ryzen CPUs. Through a support page, AMD has clarified the presence of two problems directly linked to the poor performance of Ryzen processors under Windows 11.

The first concerns the latency of the L3 cache. The applications concerned may see a decrease of 3% to 5% of their normal performance. AMD then specifies that Ryzen CPUs encounter some compatibility problems with Windows 11 in some eSports video games, and shows a performance drop of upto 15%.

There is another benchmarking company called UL Procyon that has confirmed that the performance issues in Windows 11 are happening due to Virtualization-based Security (VBS), which is enabled by default in the operating system.

So, in order to reduce the performance problems, you can try to turn off VBS in Windows 11 by following the steps mentioned below. This is a temporary fix for the time being. Microsoft and AMD have confirmed that they are working on fixes resolving these various problems impacting the performance of Ryzen processors under Windows 11.
