Recently, Microsoft, through yet another Windows update, “broke” Nvidia graphics cards, significantly reducing performance in a number of games. Now Nvidia has released a hotfix, which brings everything back to normal.
Microsoft quietly acknowledged the presence of problems in a large number of Windows 11 components. These appeared back in summer.
GeForce Hotfix version 581.94 is not a new driver version, so it must be downloaded manually from the company’s website. Nvidia itself does not specify the details, only saying that the fix should resolve the performance problem in some games caused by the Windows 11 October 2025 KB5066835 (5561605) update.
Meanwhile, some users have already compared the performance and confirmed that the increase can be more than one and a half times.
Understanding the Root Cause
The Windows 11 update KB5066835, rolled out in October 2025, aimed to address various issues but inadvertently affected Nvidia’s GPU driver operations. This update brought substantial optimizations, yet compromised graphical processing in certain gaming applications.
The Industry’s Reaction
Gaming enthusiasts and professionals alike have expressed palpable relief upon the rollout of Nvidia’s hotfix. A spokesperson from Nvidia, commenting anonymously, shared that they prioritize “swift rectification” to maintain trust among their customer base, emphasizing that such collaborative fixes are vital in rapidly evolving tech landscapes.
- Game developers have also noted positive feedback loops from users, suggesting a more seamless gaming experience post-hotfix.
- Online gaming forums are abuzz with comparisons, from frames per second (FPS) metrics showing marked improvement.
The Path Forward
Looking ahead, Microsoft and Nvidia signal collaborative testing efforts aimed at preventing similar issues. Prompt future updates are expected to refine and enhance system integrability further, ensuring users enjoy a glitch-free experience.
