Microsoft has confirmed gaming performance issues and is working to fix them on systems running Windows 11 22H2.
According to the company, the drop is likely due to some apps and games inadvertently including GPU performance debugging features "that are not intended for consumer use".
Affected customers can get around the problem by updating games and apps to the latest version available. Most will update automatically through the app shop or at launch. However, in individual cases, customers may need to consult with the developer, Microsoft added.
The company has added a compatibility hold (security IDs 41766570 and 41990091) that will prevent the upgrade to Windows 11 version 22H2 from being offered and running on vulnerable systems. Customers are advised not to install the update manually using the Media Creation Tool or by clicking 'Update Now' until the issue is fixed.
In the meantime, Microsoft is working on a fix that will be released as part of an upcoming Windows update.
It was previously reported that the Windows 11 22H2 update is not working properly on PCs with Nvidia graphics cards. The system reduces the CPU load in games from 50-80% to 2-5%, which leads to bugs. Nvidia and Microsoft developers have found that the new graphics feature in Windows 11 22H2 is accidentally enabled and leads to performance issues, especially the reduced frame rate in some games. Nvidia has fixed an issue with games slowing down on PCs with GeForce graphics cards in the 517.48 video driver.
Microsoft has reported that disabling some virtualisation features in Windows 11 will help boost performance in games. The company gave tips on how to optimise gaming performance.
Meanwhile, experts at CapFrameX found a drop in performance of AMD Ryzen 7000 series processors based on Zen 4 in Windows 11 22H2. In 2021, a similar problem was detected in Ryzen 5000 series processors after the release of version 21H2.
