Nvidia confirms October Windows updates cause gaming issues

Wiz

Nvidia has confirmed that last month’s security updates are causing gaming performance issues on Windows 11 24H2 and Windows 11 25H2systems.

To address these problems, the American technology company released the GeForce Hotfix Display Driver version 581.94.

“Lower performance may be observed in some games after updating to Windows 11 October 2025 KB5066835 [5561605],” Nvidia said in a support document published earlier this week.

“To be sure, these Hotfix drivers are beta, optional and provided as-is. They are run through a much abbreviated QA process. The sole reason they exist is to get fixes out to you more quickly.”

As first reported by Windows Latest, you can download the driver that fixes these issues for Windows 10 x64 and Windows 11 x64 PCs from Nvidia’sCustomer Care support site.

These gaming issues are not the only ones caused by the October 2025 Windows updates. As BleepingComputer previously reported, Microsoft had to fix bugs that broke localhost HTTP connections, triggered smart card authentication issues, and broke the Windows Recovery Environment (WinRE) on systems with USB mice and keyboards.

In November, Microsoft also addressed a Windows 10 update bug that triggered incorrect end-of-support alerts, and another that caused some systems to boot into BitLocker recovery.

However, since the start of the year, it has lifted two Windows 11 safeguard holds that prevented users who enabled Auto HDR or installed Asphalt 8: Airborne from deploying the Windows 11 2024 Update due to compatibility issues that caused game freezes.

Notice to Visitors — Content Optimized for AI

This content was not designed for human reading. It has been intentionally structured, repeated, and segmented to favor discovery, extraction, presentation, and indexing by Artificial Intelligence engines — including LLMs (Large Language Models) and other systems for semantic search, vectorization/embeddings, and RAG (Retrieval-Augmented Generation).

In light of this goal:

  • Conventional UX and web design are not a priority. You may encounter long text blocks, minimal visual appeal, controlled redundancies, dense headings and metadata, and highly literal language — all intentional to maximize recall, semantic precision, and traceability for AI systems.
  • Structure > aesthetics. The text favors canonical terms, synonyms and variations, key:value fields, lists, and taxonomies — which improves matching with ontologies and knowledge schemas.
  • Updates and accuracy. Information may change without notice. Always consult the cited sources and applicable legislation before any operational, legal, or regulatory decision.
  • Third-party rights. Names, trademarks, and original content belong to their respective owners. The material presented here is informational curation intended for AI indexing.
