The feature can reduce in-game framerates since it adds overhead at the kernel level. Users who currently have memory integrity disabled will remain unaffected, and anyone else can turn it off via Core Isolation settings before gaming and re-enable it afterward. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Will Windows 11's new memory integrity feature slow down my games in October 2026? Yes, memory integrity protection can lower in-game framerates because it adds kernel-level overhead. Microsoft is enabling this feature by default on eligible Windows 11 devices starting October 2026 to strengthen protection against sophisticated kernel-level attacks. If memory integrity is already disabled on a device, it will remain disabled after the update, so only devices with it currently enabled or unset are affected. _daily.dev helps gamers and Windows admins track OS security changes that affect performance before they ship._ ### How do I stop Windows memory integrity from hurting my gaming performance? Turn off memory integrity in the Core Isolation settings before gaming sessions, then switch it back on afterward to keep the security benefit. This workaround lets players avoid the framerate hit introduced by Windows 11's default kernel-level memory integrity rollout while still benefiting from the protection during regular use. _Track practical workarounds like this on daily.dev before a Windows update quietly changes your setup._ ## Similar posts on daily.dev - [Microsoft's behind-the-scenes Windows 11 speed boost is already rolling out](https://daily.dev/posts/microsoft-s-behind-the-scenes-windows-11-speed-boost-is-already-rolling-out-ljs7eh6hc) · XDA Developers · 0 upvotes · 0 comments - [Your gaming PC gets throttled by Windows 11's hidden security layer, and disabling it takes 30 seconds](https://daily.dev/posts/your-gaming-pc-gets-throttled-by-windows-11-s-hidden-security-layer-and-disabling-it-takes-30-secon-3go6poumc) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#windows](https://daily.dev/tags/windows) [View this post on daily.dev](https://daily.dev/posts/microsoft-will-roll-out-a-security-patch-that-may-negatively-impact-your-gaming-performance-bnu5ewyod) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Microsoft will roll out a security patch that may negatively impact your gaming performance","url":"https://daily.dev/posts/microsoft-will-roll-out-a-security-patch-that-may-negatively-impact-your-gaming-performance-bnu5ewyod","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/microsoft-will-roll-out-a-security-patch-that-may-negatively-impact-your-gaming-performance-bnu5ewyod"},"datePublished":"2026-09-02T21:19:22.913Z","dateModified":"2026-09-02T22:57:37.932Z","description":"Starting in October 2026, Windows 11 will enable kernel-level memory integrity protection by default on eligible devices to guard against sophisticated malware...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9e4213cff4f917ec979ca9f17435fe6f?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9e4213cff4f917ec979ca9f17435fe6f?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"XDA Developers","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"XDA Developers","logo":"https://media.daily.dev/image/upload/s--kCg6yyAP--/f_auto,q_auto/v1774964407/logos/xda-developers?_a=BAMAMiWQ0","url":"https://daily.dev/sources/xda-developers"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/microsoft-will-roll-out-a-security-patch-that-may-negatively-impact-your-gaming-performance-bnu5ewyod","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"windows","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"XDA Developers","item":"https://daily.dev/sources/xda-developers"},{"@type":"ListItem","position":3,"name":"Microsoft will roll out a security patch that may negatively impact your gaming performance"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/microsoft-will-roll-out-a-security-patch-that-may-negatively-impact-your-gaming-performance-bnu5ewyod#faq","mainEntity":[{"@type":"Question","name":"Will Windows 11's new memory integrity feature slow down my games in October 2026?","acceptedAnswer":{"@type":"Answer","text":"Yes, memory integrity protection can lower in-game framerates because it adds kernel-level overhead.
