Windows 11 bug nerfs AMD Ryzen CPU Gaming performance

A Windows bug is nerfing the gaming performance of Ryzen CPUs, and Ryzen 9000 is hit hardest

A Windows 11 bug has been uncovered that is harming the performance of AMD’s Ryzen processors. This bug is known to affect AMD’s Zen 4 and Zen 5 processors, and may even impact older Zen CPUs. Hardware Unboxed has found a way to mitigate the bug, allowing them to showcase how much Windows is nerfing AMD’s latest processors. AMD’s new Zen 5 CPUs are most affected by this issue, though the bug appears to be a Zen-wide issue.

In Hogwarts Legacy, this bug has been shown to reduce the performance of AMD’s Ryzen 7 9700X by 10%. In Cyberpunk 2077, the bug reduced the performance of AMD’s Zen 4 Ryzen 7 7700X and Zen 5 Ryzen 7 9700X by around 6.5%. Some games are impacted more by this bug than others. Overall, the fix for this bug increased the gaming performance of AMD’s Ryzen 7 9700X and Ryzen 7 7700X by an average of 4% and 3% respectively.

Currently, the only way to work around this bug is to enter a special Administrator mode in Windows 11. Thankfully, AMD has confirmed that a patch for Windows is in the works. This update will address these Ryzen CPU performance issues.

So far, AMD’s Zen 5/Ryzen 9000 CPU launch has been a mess. Performance gains with Zen 5 are minimal in many areas, and a major inter-CCX latency regression has been spotted with AMD’s 12-core and 16-core high-end CPU models. So far, it feels like AMD’s Ryzen 9000 series simply wasn’t ready to launch.
