Mr. BNSoul, who updated the version of Windows 11 from 22H2 to 23H2, reported on the online bulletin board Reddit, ``Since updating from 22H2 to Windows 11 23H2, CPU performance has decreased significantly.'' According to BNSoul, as a result of CPU benchmark tests on each version, 23H2 was found to have a performance decline of about 5 to 8% in both single thread and multi thread compared to 22H2.

Ananth Acharya, who also updated to 23H2, reported issues when playing Forza Horizon 5 and Call of Duty: Modern Warfare II .

According to Acharya, when playing Forza Horizon 5, the GPU usage rate, which had been high at over 90%, suddenly dropped to 20-23%, and the FPS, which had been in the 70-80 range, dropped to 10. It has fallen to ~23. Acharya also encountered a bandwidth-related error, so he moved the game data from the HDD to the SSD, but the problem persisted.

Furthermore, in Call of Duty: Modern Warfare II, even after updating the driver to the latest version and performing a clean install of Windows 11, a problem occurred where the game crashed due to a GPU error. Acharya said, ``This problem has been occurring right after the 23H2 update, so it is likely caused by the OS.''

BNSoul claimed that ``To resolve the performance issues that occur with 23H2, it is necessary to roll back to the previous version, 22H2.'' However, after receiving reports from users, Microsoft has announced a countermeasure. I am proposing it.

The solution steps provided by Microsoft are as follows.

1: Reset

Microsoft Defender using PowerShell commands
2: Restart your PC, open the BIOS screen and enable CPU virtualization
3: Enabling memory integrity in core isolation settings from Windows Security
4: Restart your PC and the hypervisor will be running and virtualization security will be enabled

A user who executed the solution presented by Microsoft reports that ``GPU benchmarks are 3 to 5% faster than before, and CPU benchmarks are almost back to the same level as 22H2.''
