The latest iteration of Microsoft’s operating system, Windows 11 24H2, is poised to introduce a range of enhancements and improvements. However, one of the new features, Memory Integrity (VBS), has sparked debate among users and tech enthusiasts alike. Despite its security benefits, it seems that enabling this feature may come at the cost of system performance.
Enhancing Security with Memory Integrity
Microsoft has long emphasized the security aspects of Windows 11, ensuring that devices meet certain criteria like the Trusted Platform Module (TPM) and Secure Boot. To further bolster system security, the company introduced the Virtualization-Based Security (VBS) feature, which is enabled through the memory integrity check or Hypervisor-protected Code Integrity (HVCI).
This technology allows for a higher level of security by isolating critical system files from unauthorized access. It is designed to protect against certain types of malware that attempt to steal data by accessing memory.
Performance Impact of Memory Integrity
While memory integrity does enhance system security, it does so at the potential expense of performance. Microsoft has acknowledged this trade-off, as evidenced by a statement in one of its support documents. The company suggested that disabling memory integrity can help improve gaming performance, as the feature can cause a notable decrease in frame rates.
German tech website ComputerBase conducted a performance test on Windows 11 24H2 using an AMD Ryzen 5800X3D processor. The results indicated that enabling memory integrity led to a performance drop, with frame rates decreasing by approximately 8%. This reduction in performance may vary depending on the hardware configuration.
Despite the performance impact, Microsoft may consider this a reasonable trade-off for increased security. The company has made it clear that the goal is to enhance system security, even if it means sacrificing some performance.
AMD’s Efforts to Optimize Performance
Recognizing the potential performance issues with memory integrity, AMD has taken steps to optimize the feature. The company has focused on improving branch prediction functionality in Windows 11 24H2, which addresses performance issues for non-Administrator accounts.
AMD has also ported these optimizations to Windows 11 23H2, ensuring that users on older versions of the operating system can benefit from improved performance as well.
Upcoming Performance Enhancements
For AMD users, the upcoming September patch should help mitigate the performance impact of memory integrity. These patches are expected to be released next week and will likely provide users with a more balanced experience between security and performance.
Conclusion
The Windows 11 24H2 update brings a range of new features and enhancements, but it also raises questions about the trade-offs involved in using certain features like memory integrity. While the security benefits are clear, users may need to weigh the performance impact before enabling this feature on their systems.
AMD’s efforts to optimize performance for memory integrity are a positive step, and the upcoming patches should provide users with a better balance between security and performance. As always, it’s important for users to stay informed about the latest updates and to make informed decisions about their system configurations.
