Microsoft released the Windows 11 23H2 update, bringing numerous new features and fixes. However, apparently the update did not have the expected effect for every user. Some users have begun to report that they are experiencing a general performance drop in games on their Windows 11 devices. Users state that the performance problem persists even after a clean installation and is not due to a thermal reason.Windows 11 23H2 drops gaming performance
Some of the users who voiced their problems on the official Microsoft forums claim that the 23H2 clean install is 5 to 8 percent slower than 22H2 in almost all benchmarks. In addition, games experience random stutters and other performance-related issues. Although the ultimate solution is to revert to the previous version, Microsoft has also offered a temporary solution.
According to the company, users should reset Microsoft Defender with a few PowerShell commands, restart their PC, and then enable CPU Virtualization in the BIOS. Next, users need to open Windows Security and enable Memory Integrity under Core Isolation settings. After making the changes mentioned above, when the computer restarts, Hypervisor will be running and Virtualization Security will be enabled. Microsoft and most users who tried this workaround report that these steps worked. You can access the relevant commands from the source section or here.
