Key settings to check include enabling XMP/EXPO memory profiles for rated RAM speeds, tuning fan curves for better thermal balance, turning on Resizable BAR for up to 10% gains (especially important for Intel Arc GPUs), enabling AMD Precision Boost Overdrive or Intel Multi-Core Enhancement for extra CPU performance, and verifying Secure Boot is enabled for security and multiplayer game requirements. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Does enabling Resizable BAR actually improve gaming performance? Yes, enabling Resizable BAR can improve gaming performance by up to 10% depending on the game, though the benefit varies by GPU. Some cards benefit more than others, and Intel Arc GPUs essentially require Resizable BAR to be enabled, since performance struggles significantly without it. _Gamers deciding whether to flip on Resizable BAR can compare real-world impact reports on daily.dev._ ### What is the difference between AMD Precision Boost Overdrive and Intel Multi-Core Enhancement? AMD Precision Boost Overdrive (PBO) is a broader set of tunable settings covering boost overrides and per-core undervolting, giving flexible but less predictable CPU tuning. Intel Multi-Core Enhancement (MCE) is a simpler on/off toggle that forces all cores to run at their highest turbo frequency, giving a predictable performance boost at the cost of higher heat and power draw. _Builders comparing CPU tuning options can track AMD versus Intel platform differences on daily.dev._ ## Similar posts on daily.dev - [I change these 4 BIOS settings on every PC I build, and they make a real difference](https://daily.dev/posts/i-change-these-4-bios-settings-on-every-pc-i-build-and-they-make-a-real-difference-yzu27j3w3) · XDA Developers · 0 upvotes · 0 comments - [Check your BIOS defaults before blaming Windows for bad PC performance](https://daily.dev/posts/check-your-bios-defaults-before-blaming-windows-for-bad-pc-performance-kwabbmwpy) · XDA Developers · 0 upvotes · 0 comments - [My motherboard’s default BIOS settings were secretly killing my gaming experience](https://daily.dev/posts/my-motherboard-s-default-bios-settings-were-secretly-killing-my-gaming-experience-0akcpzngt) · XDA Developers · 20 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#gaming](https://daily.dev/tags/gaming), [#hardware](https://daily.dev/tags/hardware) [View this post on daily.dev](https://daily.dev/posts/5-bios-settings-gamers-forget-to-change-sswvjgvgx) ```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":"5 BIOS settings gamers forget to change","url":"https://daily.dev/posts/5-bios-settings-gamers-forget-to-change-sswvjgvgx","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/5-bios-settings-gamers-forget-to-change-sswvjgvgx"},"datePublished":"2026-09-02T13:30:50.592Z","dateModified":"2026-09-02T13:43:09.164Z","description":"Gamers often skip revisiting their BIOS after building or buying a PC, missing out on free performance and stability gains.
