At this point, it’d be a bit odd if a massive Windows update such as Windows 11 didn’t cause major problems, so issues with performance should not come as a shock. Windows 11 version 21H2 or Version 22000.194 has caused massive performance slowdowns Internet issues, performance issues, and a variety of other issues for some users.

It was released on October 5th. Windows 11 is the latest version of the operating system. it includes a brand new menu for starting, a notification center as well as a taskbar that has been upgraded. Benchmarks had previously suggested it was possible that Windows 11 will be slightly more efficient over Windows 10, but AMD has now confirmed the slowdowns in the system.

AMD along with Microsoft are looking into the reports about Windows 11 performance issues. According to a support guideline released by AMD, Windows 11 could affect the performance of specific applications.

According to in the report, L3 memory latency could rise by three times and could impact the performance of applications that use memory. AMD expects to see a performance impact of 3 percent in some apps as well as games that be slower by up to 10 10%.

Microsoft plans to solve these issues within the next update cumulative which is expected to roll out in the month of October 2021.

An additional Windows 11 bug seems to hinder performance by not recognizing CPU threads. AMD has noticed that apps that are sensitive to CPU threads could have issues with performance. The issues are evident when you update your machine however, the configurations of different configurations may not be affected.

“Performance impacts could be more evident when a processor has more than eight cores that exceed 65W TDP. An update to the software is currently in development to fix this issue and is scheduled release in October of 2021.” AMD said.

If you’re using Windows 10, you may be advised to put off the upgrade up to Windows 11 version 21H2 (original version) until Microsoft has resolved or provided an alternative solution to the performance issues. If you’re experiencing issues, AMD recommends waiting for updates to the software that is available from AMD or Microsoft.

In addition to AMD, benchmarking company UL Procyon has confirmed that a feature in Windows 11 called “Virtualization-based Security (VBS)”, which is now enabled by default, causes performance to drop. In the end, the benchmark scores could be lower when benchmarking Windows 11 version 21H2 with VBS enabled.

For those who aren’t aware that Virtualization-based security (VBS) is an advanced feature of hardware virtualization that permits Windows to provide additional security options and safeguard Windows from vulnerabilities that are known to exist.

VBS is also employed to limit malicious exploits and remote access attempts made by attackers.

Evidently, Windows 11 now enables VBS on new devices as well as clean installations. This is affecting the performance of devices using Windows 11.

If you’re moving from Windows 10 to Windows 11 from Windows 10 There won’t be any performance problems.

To lessen the impact on performance to reduce performance impact, you can disable VBS using these methods:

  1. Open Windows Search.
  2. Look up the Core Isolation to enable Windows Security.
  3. Switch off your Memory Integrity feature and then restart your computer.
  4. Start the Registry Editor and move to the following address.
  5. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\DeviceGuard
  6. Double tap on EnableVirtualizationBasedSecurity and set it to 0.
