Windows 11 Gaming Performance Guide: Game Mode, DirectStorage, Auto HDR, and More

Windows 11 ships with a focused toolkit for PC gaming — from Game Mode and Auto HDR to DirectStorage and per‑app GPU control — and when you combine those features with up‑to‑date drivers, the right power profile, and thoughtful storage management you can measurably boost FPS, reduce stutters, and cut load times. Enabling the right settings, matching each game to the correct GPU, keeping game files on an NVMe drive that supports DirectStorage, and avoiding unnecessary background work are the practical wins that separate a smooth session from a frustrated one.

Background​

Windows 11 consolidated a set of gaming‑focused features Microsoft and hardware vendors developed in recent years. These include:

• Game Mode — prioritizes CPU and system resources for a foreground game.
• Auto HDR — lifts SDR titles into an HDR presentation on compatible displays.
• DirectStorage — reduces load times by feeding assets to the GPU more efficiently (when both the OS, hardware and the game support it).
• Per‑app GPU selection and Hardware‑Accelerated GPU Scheduling (HAGS) — let Windows and driver stacks route workloads optimally.

All of these are implemented in the OS and exposed via Settings, but their effectiveness depends on drivers, firmware, the display and how the user configures storage and power options. The improvements are real for compatible setups, but they are not automatic — you still need to tune the system and verify each change for your hardware and games.

Core Windows 11 settings every gamer should check​

Game Mode — the first stop for smoother FPS​

Game Mode tells Windows to prioritize your game over most background work. It’s lightweight, simple to enable and is one of the easiest steps to take for a quick improvement in responsiveness.
How to enable:

• Open Settings → Gaming → Game Mode and toggle On.

Why it matters: Game Mode reduces system interruptions and can improve consistency of frame delivery. It doesn’t create miracles, but as part of a broader tuning pass it helps reduce variance caused by background tasks.

Auto HDR and HDR workflow​

If your monitor or TV supports HDR, turning on Auto HDR can dramatically improve color, contrast and perceived detail in games that weren’t built specifically for HDR.
How to enable:

• Settings → System → Display → toggle Use HDR, then find Auto HDR options and enable them when available.

Caveats: Not every title benefits; some older games may display washed out colors if HDR is misconfigured. Always confirm the display is HDR‑capable and that Windows reports HDR status before assuming benefits.

DirectStorage — the NVMe speed boost (requirements and reality)​

DirectStorage reduces load and streaming stalls by allowing bulk game assets to bypass some CPU work and be transferred quickly to the GPU. It delivers the largest gains when a game explicitly implements DirectStorage and the game files are installed on a compliant NVMe SSD.
Key points:

• You need an NVMe drive (PCIe) and a game that supports DirectStorage for visible gains. The OS support is a necessary but not sufficient condition.
• Expect the clearest wins in open‑world or asset‑heavy titles where load and streaming are bottlenecks; smaller games will show little difference.

Per‑app GPU selection and HAGS​

Windows 11 lets you assign each executable to use the integrated GPU or discrete GPU, and HAGS (Hardware‑accelerated GPU Scheduling) can reduce driver latency on supported configurations.
How to use per‑app GPU selection:

• Settings → System → Display → Graphics → Add the game executable and choose High performance to force discrete GPU use. Verify in Task Manager (GPU engine) that the game is actually using the discrete GPU.

About HAGS:

• HAGS is supported only on newer drivers and hardware. It can help reduce latency in some cases but has been reported to cause instability on certain driver+hardware combinations — test before you adopt it permanently.

Power plans — Best Performance / High performance​

By default Windows uses balanced power behavior; switching to a higher performance profile prevents the OS from throttling CPU/GPU clocks during intense scenes.
How to set:

• Settings → System → Power & battery → select Best performance (or in Control Panel → Power Options choose High performance on desktops).

Note: On laptops the increased power draw will reduce battery life and raise temperatures; use this profile while plugged in.

Drivers and vendor software — the performance edge​

Keeping GPU drivers current is among the highest ROI tasks for gamers. Vendor control panels (NVIDIA GeForce Experience, AMD Radeon Software, Intel Graphics Command Center) offer per‑title optimizations and streaming/encode improvements that Windows alone can’t provide.
Best practices:

• Use driver downloads from the GPU vendor. For NVIDIA, know the difference between Game Ready and Studio drivers; pick the one that fits your use case. For AMD, follow Radeon Software release notes for game‑specific optimizations.
• When a recent driver causes instability, perform a clean driver reinstall using DDU (Display Driver Uninstaller) in Safe Mode, then install the vendor package. This avoids corruption from layered driver artifacts.
• Use vendor overlays sparingly: GeForce Experience, Discord, and similar overlays consume resources and can interfere with some titles — disable them when troubleshooting frame drops.

---

Storage: free up C:, move games, and use Storage Sense​

Modern games are large and benefit from fast storage. A crowded system drive can cause pagefile activity, longer load times, and occasional stutter.
Practical steps:

• Use Storage Sense to remove temporary files and old Windows update artifacts. Settings → System → Storage → Storage Sense.
• Keep large game installations on a fast NVMe drive when possible — this is especially important for DirectStorage gains. Confirm the game supports DirectStorage and that the installed path is on the NVMe.
• If you need more system drive space, you can resize partitions with reputable tools — many opt for EaseUS Partition Master — but that is a third‑party option; you can also use built‑in Disk Management or clone drives using vendor utilities. When using third‑party tools, back up first and follow vendor instructions precisely.

Caution: resizing or moving system partitions can break boot configurations if done incorrectly. Create a recovery drive and a full backup before manipulating partitions.

Networking, latency and online play​

Network quality matters as much as local performance for online multiplayer.

• Prefer a wired Ethernet connection for competitive gaming — it reduces jitter and packet loss versus Wi‑Fi.
• Disable background downloads (Windows Update, store downloads, cloud sync) before important matches. Prioritize game traffic with router QoS where possible.
• If you have persistent high latency, test with alternate DNS providers and check your ISP’s peering routes for problem times; a local wired upgrade or a better router can yield immediate improvements.

Security trade‑offs and advanced toggles — proceed with care​

Some Windows security features improve protection but add measurable overhead. The most commonly discussed examples for gamers are Memory Integrity (Core isolation) and Virtual Machine Platform (VMP).
What the files say:

• Disabling Memory Integrity can reduce CPU overhead in some systems, but it increases attack surface. It is advisable to disable it only temporarily for troubleshooting or high‑performance sessions and re‑enable it afterwards. The Windows Security app exposes the toggle under Device Security → Core isolation details.
• Turning off Virtual Machine Platform (from Windows Features) can be used to recover performance in some configurations, but it will break WSL2, Android subsystem features or other virtualization‑dependent services if you rely on them.

Security guidance:

• Never disable protections permanently on a system that connects to the internet regularly. If you must disable for a gaming session, create a plan to re‑enable them and ensure the system is otherwise behind a secure network during the window you’re exposed.

Advanced performance tuning (with warnings)​

For experienced users willing to accept additional risk and monitoring overhead, consider:

• Overclocking GPU/CPU with proper cooling and incremental testing. Overclock conservatively and use telemetry like MSI Afterburner to monitor temps and frame timings. Overclocking increases heat, power draw and can shorten component life.
• Disable in‑game overlays (Xbox Game Bar, Discord, GeForce overlay) — they often cost CPU cycles and can create compatibility problems. You can remove the Xbox Game Bar via PowerShell, but take care — removing built‑in apps may require extra steps to restore them later.
• Use "Disable fullscreen optimizations" on problematic games: right‑click the game's .exe → Properties → Compatibility → check Disable fullscreen optimizations. This can help older titles that behave poorly under Windows’ optimization layer.

Always perform one change at a time and benchmark between changes to isolate what actually moves the needle.

Testing, benchmarking and troubleshooting methodology​

Good measurement practices separate myth from reality.

• Record a baseline: run a reliable benchmark or in‑game benchmark and log average FPS, percentile frame timing (1%/0.1% lows) and load times before changes. Use Windows Performance Monitor, MSI Afterburner/RivaTuner for telemetry and in‑game benchmarks where available.
• Change one setting and retest: change only one variable per test cycle so you can attribute gains or regressions reliably.
• If a change increases crashes or visual anomalies, revert immediately and test whether a driver rollback stabilizes the system (DDU + clean driver install is a reliable path).
• Keep a stable driver version for your primary titles; frequent driver churn can introduce regressions even as it adds new features.

---

Step‑by‑step optimization checklist (recommended sequence)​

• Update Windows (Settings → Windows Update) and reboot.
• Update GPU drivers from the vendor (or use GeForce Experience / Radeon Software), or perform a clean reinstall if you’re troubleshooting.
• Ensure Game Mode is enabled (Settings → Gaming → Game Mode).
• Set power plan to Best performance / High performance and plug in laptops.
• Move heavy games to an NVMe drive if you have one (and confirm DirectStorage support for the title).
• Configure per‑app GPU preference for each game to High performance and verify in Task Manager.
• Enable HAGS if supported and test stability; roll back if you encounter regressions.
• Disable unnecessary overlays and background services (Spotify, cloud sync, browser tabs) before sessions.
• Benchmark and compare results; keep a changelog of what you modified.

---

Risks, trade‑offs and common pitfalls​

• Security vs. Performance: Disabling Memory Integrity or virtualization features reduces protection. If you disable them for performance, re‑enable them as soon as possible.
• Driver volatility: the newest driver is not always the best for every system. Validate with your primary games and be ready to roll back.
• Overzealous cleanup: removing built‑in apps or system components can lead to unexpected behavior and complicate later troubleshooting. Document changes and keep restore points.
• Tool risk: third‑party partitioning tools or “one‑click” optimizers carry risk — back up and prefer vendor‑recommended utilities where possible.

Final analysis — where Windows 11 shines and what to watch​

Windows 11 consolidates several meaningful improvements that benefit gamers: tighter integration with Xbox ecosystem features, clearer in‑OS controls for GPU and power behavior, and OS support for DirectStorage and Auto HDR. When combined with current vendor drivers and a fast NVMe drive, these features can deliver quicker load times, richer visuals and more consistent frame delivery.
At the same time, the landscape is fragmented: driver maturity, vendor control panel behavior and individual game implementation determine the size of gains. Features like HAGS and DirectStorage require compatible hardware and driver stacks — and on some systems HAGS has shown regressions, so testing and careful rollbacks are essential. Security toggles that reduce overhead also increase exposure; treat them as temporary troubleshooting tools, not permanent performance shortcuts.

Conclusion​

Optimizing Windows 11 for gaming is a practical process: enable built‑in features like Game Mode, Auto HDR, and per‑app GPU selection; keep GPU drivers current and prefer vendor tools for per‑title tweaks; move demanding titles to an NVMe drive and verify DirectStorage support; and adopt a careful, test‑driven approach to advanced changes such as HAGS, partition resizing or disabling security features. Each change yields incremental improvements; combined they produce a noticeable uplift in FPS, reduced stutter and faster loads. Always balance performance gains against system stability and security — measure, document and be ready to revert if a tweak introduces instability.
By following this structured checklist and testing one variable at a time, most players will squeeze meaningful improvements from Windows 11 while keeping their systems secure and reliable.
