Microsoft’s Windows 11 24H2 update, which launched with high hopes, has encountered serious issues that are causing significant performance drops for some users. Among the most impacted systems are those running Intel’s latest Core Ultra 9 285K CPUs, where gamers and power users are experiencing slowdowns and crashes. This article dives deep into the performance degradation, who or what is to blame, and whether these issues are exclusive to Windows 11 or a result of conflicts with Intel’s latest chipsets.

Summary:

The recent updates for Windows 11 24H2, specifically patches KB5050094 and KB5051987, have caused severe performance degradation, particularly with Intel’s latest Core Ultra 9 285K processors. Users have reported crashes and instability, especially in gaming applications like The Settlers: New Allies. In some cases, systems equipped with the Core Ultra 9 285K were unable to even launch after installing these updates, pointing to issues with Intel’s microcode integrated into the BIOS.

Even after systems were up and running, users experienced substantial performance throttling. Applications, when minimized or out of focus, experienced massive CPU clock rate drops, causing a severe decrease in performance. This issue was not confined to one specific application, with benchmarks like 7Zip and Prime95 also showing significant drops in performance. Interestingly, the issue didn’t appear in systems running AMD Ryzen CPUs or older Intel Core i9 models, indicating a possible compatibility issue specific to Intel’s latest LGA 1851 platform.

Unfortunately, no solid fix is available as of now, although some users have found a workaround by adjusting power settings to maintain “full CPU performance” during background processes. However, this isn’t a long-term solution and raises questions about the stability of the latest Windows 11 build. Given the performance issues and crashes, users facing these problems are advised to consider reverting to a previous, more stable version of Windows 11 until further fixes are made.

What Undercode Says:

The current problems with Windows 11 24H2 present a concerning trend in Microsoft’s software updates, particularly when paired with Intel’s newest hardware. The Intel Core Ultra 9 285K processors seem to be at the center of these issues, and it’s apparent that the problems may not stem from a singular cause but rather a combination of software and hardware mismatches. While Intel’s latest chipsets are cutting-edge, the issue with performance throttling, CPU clock-rate drops, and application instability highlights potential flaws in how these chips interact with Windows 11, especially in terms of energy management and resource allocation.

What’s worrying is the recurrence of issues with Windows 11 updates. Users have been facing growing concerns with Windows 11 ever since its release, and the latest update is no exception. Microsoft’s track record of rolling out updates that introduce new bugs or cause hardware compatibility issues is becoming a growing concern. In the case of the 24H2 update, the problem seems more pronounced with Intel’s newer hardware, though it’s possible that the issue lies in how the update interacts with the microcode update tied to the BIOS.

It’s also worth noting the lack of significant fixes or official responses from either Microsoft or Intel, leaving users frustrated and vulnerable to issues with their systems. As of now, there’s no clear indication from either company about when a more comprehensive solution will arrive. The fact that users are resorting to workarounds, such as adjusting power settings to maintain high performance, speaks volumes about the severity of the issue.

Additionally, the way these issues have affected high-performance applications like 7Zip and Prime95 suggests that the throttling is not isolated to gaming but impacts a broad range of workloads. This is problematic for power users who depend on smooth, consistent performance across various applications. The recommendation to revert to older versions of Windows 11 may provide some relief, but this is a temporary solution that doesn’t address the root cause.

Despite the severity of the issue, it’s important to note that it isn’t affecting all Intel systems. Users with older Intel chips or AMD processors seem to be largely unaffected, pointing to the possibility that the issues are exclusive to the newer Intel LGA 1851 platform. Still, the widespread nature of crashes and performance drops cannot be ignored, and this highlights the need for more robust testing before major OS updates are released.

Fact Checker Results:

  • Performance Issues Confirmed: Multiple reports from affected users support the claim of CPU throttling and performance drops after the update.
  • Intel-Specific Problem: The issue seems to be particularly affecting Intel’s Core Ultra 9 285K processors, not AMD systems or older Intel chips.
  • No Official Fix Yet: As of now, no comprehensive fix has been released, with users resorting to temporary workarounds like power setting adjustments.
