This guide walks through what the important Windows settings actually do, when they're worth touching, and how to properly investigate a PC that isn't performing the way you'd expect. It also covers popular "gaming tweaks" that are better left alone unless you have a specific, measured reason to use them.

Is Windows 11 actually good for gaming in 2026?

Yes — for a compatible PC, it's the practical choice now. It supports current graphics drivers and gaming features, and it's still inside normal security and feature support.

Windows 10 reached the end of normal support on 14 October 2025. Eligible consumer PCs enrolled in Microsoft's Extended Security Updates programme can keep receiving critical and important security fixes through 12 October 2027. ESU doesn't bring new features or general technical support back; it's breathing room rather than a return to normal support. Microsoft explains the current position on its Windows 10 Extended Security Updates page.

For anyone with an NVIDIA card specifically, the operating system's own security coverage is only half the story. NVIDIA's final regular Game Ready Driver that supports Windows 10 is due in October 2026, with the first Game Ready release that drops Windows 10 arriving the following month. After that, Windows 10 moves to quarterly NVIDIA security updates, including critical bug fixes, through October 2029.

Nothing currently installed suddenly stops working, but Windows 10 users shouldn't expect the usual stream of game-specific Game Ready releases after October 2026. NVIDIA sets out the timetable in its GeForce support plan for Windows 10.

None of that is the same as saying Windows 11 hands you a dramatic FPS boost. A 2026 TechSpot/Hardware Unboxed comparison across 14 games found Windows 11 25H2 modestly ahead of Windows 10 22H2 on its high-end test system — roughly 4–5% on average depending on resolution. Individual games varied, and the test setup wasn't a default fully secured Windows installation either.

Treat that sort of result as evidence that Windows 11 is no longer a gaming disadvantage, not as a promise that changing operating system will give your own PC the same percentage improvement. You can see the full Windows 11 versus Windows 10 gaming benchmark for the individual results.

For most existing gaming PCs, Windows 11 25H2 remains the broadly relevant version. Microsoft has also released Windows 11 26H1 for selected new devices that shipped in 2026, but it isn't offered as an in-place update from 24H2 or 25H2.

In plain English: if your fully updated PC still reports 25H2, that doesn't necessarily mean you've somehow missed an upgrade. Stable drivers and game compatibility matter more than trying to force a version of Windows intended for different hardware. Microsoft explains the distinction on its Windows 11 release information page.

The settings worth checking first

Do these before you go anywhere near an "optimiser" tool or the registry. They fix genuine configuration mistakes and give you something reliable to build on.

Set the display to its proper refresh rate

A 165 Hz monitor can quietly sit running at 60 Hz if Windows was never told otherwise. It won't change the FPS your game reports, but it caps how many distinct frames the screen can actually show and makes motion feel less responsive than it should.

Go to Settings → System → Display → Advanced display, pick the correct monitor, and select its intended refresh rate.

If the rate you expect isn't listed:

• Check that the cable and port support that resolution and refresh rate together.
• Install the current GPU driver.
• Check the monitor's own on-screen menu for a high-refresh or DisplayPort mode.
• Check whether duplicating displays is forcing them to a shared, lower mode.
• Confirm the game's own display, refresh-rate and frame-cap settings aren't the real cause.

Windows may also offer Dynamic Refresh Rate on compatible 120 Hz-or-faster displays. It varies the desktop refresh rate to save power, and Microsoft's guidance notes that it can limit the maximum refresh rate of some games. If a title seems stuck below where it should be, turn DRR off and retest before assuming something else is wrong. Microsoft provides the current setting path in its refresh-rate guide.

Update deliberately, not compulsively

Run Settings → Windows Update → Check for updates after a fresh installation, restart, and repeat until everything important is actually done. Install the correct chipset and GPU drivers from the PC, motherboard or GPU manufacturer while you're at it.

For graphics drivers, "newest" earns its place when the release notes mention a game you actually play, a bug you're hitting, or support for a title you're waiting on. Installing a driver that appeared five minutes ago immediately before a tournament is a different matter.

• NVIDIA: Game Ready drivers prioritise new-game support; Studio drivers prioritise tested creative-application stability. Both can run games, so start with the branch that suits what the machine is mainly used for.
• AMD: use AMD Software or AMD's official auto-detect tool for supported Radeon hardware.
• Intel: use Intel's current graphics tools, but remember that laptop manufacturers sometimes provide customised driver packages for hybrid graphics and power behaviour.

If performance became worse immediately after a graphics-driver update, resist piling more tweaks on top to compensate. Go to Device Manager → Display adapters → [your GPU] → Properties → Driver → Roll Back Driver if the button is available, and retest. An ordinary reinstall or rollback should come before reaching for aggressive driver-removal tools.

Make sure the game is actually using the right GPU

This matters most on laptops and PCs using both integrated and dedicated graphics.

Go to Settings → System → Display → Graphics, add or select the game, open Options, and choose High performance if Windows has assigned it to the low-power GPU. Restart the game after changing it.

On a desktop with one active GPU, this setting normally does nothing either way.

Laptop owners should also:

• Connect the original, properly rated mains adaptor.
• Use the manufacturer's Balanced or Performance profile while gaming.
• Check whether an OEM hybrid, discrete-GPU or MUX-switch mode requires a restart.
• Keep vents clear and watch CPU/GPU temperatures and clock behaviour.
• Expect performance to drop on battery even when Windows reports Best performance mode.

Power mode itself lives at Settings → System → Power & battery → Power mode. Best performance allows more aggressive behaviour at the cost of increased power draw, fan noise and heat. It's genuinely useful for a plugged-in, power-limited laptop; it isn't a free desktop FPS boost waiting to be claimed.

Leave Game Mode on unless testing tells you otherwise

Find it at Settings → Gaming → Game Mode. Its job is to help maintain a consistent gaming session and reduce disruptive background activity such as update interruptions — not guarantee extra frames.

The sensible default is On. If one particular game, capture tool or streaming setup misbehaves, test the same repeatable scene with Game Mode on and off and keep whichever result is measurably better on that machine. Don't turn one unusual result in one game into a universal rule.

The Windows 11 gaming features actually worth knowing about

Optimisations for windowed games and Variable Refresh Rate

Plenty of players use borderless windowed mode for quick Alt-Tab switching. Windows 11's Optimisations for windowed games feature moves compatible DirectX 10 and 11 windowed or borderless titles from an older presentation path to the modern flip model. That can reduce frame latency and enable features such as Auto HDR and Variable Refresh Rate. DirectX 12 games already use the newer presentation model.

Find it at Settings → System → Display → Graphics → Default graphics settings. The exact final label can vary slightly between Windows builds. Enable Optimisations for windowed games.

If one particular title starts glitching, return to Graphics, select that app, open Options, and disable the optimisation for that game specifically rather than switching it off globally. Restart the game after making a change.

VRR — sold under names such as AMD FreeSync and NVIDIA G-SYNC — synchronises the display's refreshes with the frames actually being delivered inside its supported range. Its main benefit is smoother presentation with less tearing, not a higher average FPS. Enable the appropriate mode in the monitor's own menu and GPU software first.

Hardware-accelerated GPU scheduling: worth testing, not worshipping

Hardware-accelerated GPU scheduling, usually shortened to HAGS, lets a supported GPU take on more of its own scheduling work. It needs a compatible GPU and driver to appear as an option, and you'll find it under Settings → System → Display → Graphics → Default graphics settings.

Microsoft's own explanation describes this as a significant architectural change intended to be largely transparent to the user — not a switch expected to deliver huge performance improvements on its own. You can read Microsoft's technical explanation of HAGS for the detail.

Results can genuinely vary by GPU, driver and game. Start with whatever Windows defaults to. If you're chasing repeatable stutter, poor frame pacing or an interaction with capture or streaming software, benchmark the same scene with HAGS on and off, restarting Windows between tests.

Keep whichever result measurably wins. A single higher number from one variable multiplayer match proves very little.

DirectStorage isn't an "enable faster games" switch

DirectStorage is an API: game developers have to build support for it themselves. It isn't something Windows can retroactively bolt onto every title.

Where it's implemented, DirectStorage allows a game to move and decompress asset data more efficiently, with NVMe storage providing the greatest opportunity for improvement. Newer versions can also use GPU decompression on compatible DirectX 12 hardware.

There is no general "DirectStorage on" toggle sitting in Windows waiting for you to find it. A game either supports it or it doesn't. Keep supported titles on an SSD — preferably NVMe where the developer recommends it — and leave enough free space for updates and shader caches.

Expect potential improvements to loading and asset streaming, not a blanket FPS increase across your entire library. Microsoft explains the technology in its DirectStorage for PC guide.

Auto HDR and HDR Calibration: presentation, not speed

Auto HDR can widen the brightness and colour range of compatible older SDR DirectX 11 and 12 games, provided you actually have an HDR-capable display.

Go to Settings → System → Display, select the HDR display, open HDR, enable HDR, then enable Auto HDR if it's offered.

It doesn't work with every game, and a mediocre or poorly calibrated HDR display can genuinely look worse than SDR. Microsoft's Auto HDR guidance explains the supported setup.

If you use HDR, run Microsoft's Windows HDR Calibration app full-screen on the HDR display. It walks you through black level, peak brightness and saturation and is worth running before you start changing every game's HDR settings individually.

If HDR looks washed out or the expected refresh rate disappears, check the monitor's input mode, cable bandwidth, GPU output settings and driver. High resolution, high refresh rate, HDR and high bit depth together can exceed what an older port or cable can carry.

Game Bar is fine; recording is what uses resources

Windows key + G opens Xbox Game Bar, including capture controls, audio controls and performance information. Its presence alone isn't a reason to start removing Windows components.

If you don't record clips, look at Settings → Gaming → Captures and turn off background recording you aren't using. Encoding video uses some CPU or GPU resource and writes data to storage, but the actual impact depends on the encoder, resolution and hardware.

If you stream or record, measure game performance with your real capture setup running rather than disabling software you genuinely need just to chase a benchmark number.

What each change can realistically do for you

Different settings affect different parts of the experience. Something that improves frame delivery, loading time or image quality isn't necessarily increasing average FPS at all.

A sensible order for tracking down poor FPS or stuttering

Changing five things at once destroys your own evidence. Work through this in order, and retest after each step rather than stacking changes on top of each other.

1. Define the actual symptom and get a baseline

"It feels slow" could mean low average FPS, poor 1% lows, regular hitching, input lag, tearing, or simply a display stuck at 60 Hz. These are genuinely different problems with different fixes.

Use the game's built-in benchmark if it has one. Otherwise choose a repeatable offline scene and record:

• Resolution, graphics preset, upscaler and frame-generation settings.
• Display mode, V-Sync and any frame cap.
• Average and 1% low FPS if the game reports them.
• Whether a hitch happens once or repeatedly.
• CPU, GPU, memory and disk activity.
• CPU and GPU temperatures and clock speeds.

Change one thing at a time from here. A busy multiplayer match is poor evidence because the workload changes on every run — you aren't comparing like with like.

2. Rule out the simple stuff first

Confirm the display is actually running at the expected refresh rate, the game is using the resolution you think it is, and there isn't a frame cap set in both the game and GPU software.

Check whether the game silently increased its render scale or switched on an expensive ray-tracing preset after an update. On a laptop, make sure it's plugged in and the dedicated GPU is active. On a desktop, double-check that the monitor cable is connected to the graphics card rather than the motherboard if you expect the dedicated GPU to be doing the work.

3. Find out what's actually the bottleneck

Open Task Manager with Ctrl + Shift + Esc, switch to Performance and Processes, and reproduce the problem while watching what happens.

• GPU near full utilisation: the graphics workload is probably your current limit. Try reducing resolution, ray tracing or the heaviest quality settings, and use the game's supported upscaler where appropriate.
• Low GPU utilisation: this does not automatically mean Windows is broken. The game may be CPU-limited, capped, waiting on shader compilation, using the wrong GPU or stalled by storage.
• Very high memory use plus disk activity: this can indicate paging pressure. Close an unnecessary memory-heavy application before changing Windows internals.
• A process repeatedly spiking CPU, GPU or disk when the hitch occurs: that's a genuine lead. Investigate it rather than disabling every service you can find.
• Falling clock speeds with rising temperatures or a visible power limit: look at cooling or power delivery, particularly on a laptop.

4. Work backwards from whatever changed last

If the problem appeared suddenly, ask what changed immediately beforehand: the game itself, a mod, GPU driver, Windows update, BIOS update, overlay or capture software.

Settings → Windows Update → Update history gives you dates to work from. Microsoft's Windows Release Health pages track known problems, and GPU manufacturers publish their own driver release notes.

Microsoft records the details on its Windows 11 25H2 resolved-issues page.

Roll back a suspect graphics driver first before doing anything more drastic. Removing a recent Windows update should generally be reserved for a documented, serious regression because doing so can also remove security fixes.

5. Remove competing software one thing at a time

Disable an overlay, hardware-monitoring hook or background recording feature one at a time and retest between each change. Only quit launchers once the game genuinely no longer needs them running.

Don't assume every overlay is guilty by default. Check Task Manager → Startup apps or Settings → Apps → Startup, and disable only software you recognise and don't need at sign-in. Task Manager's startup-impact label is a useful way to prioritise what is worth checking.

If you're still investigating a suspected software conflict, Microsoft's documented clean boot procedure is a much better diagnostic tool than permanently switching off a long list of services you don't understand.

A clean boot is a temporary diagnostic state, not a permanent gaming mode.

6. Let the symptom point you to the next test

• Poor performance only on battery: this is usually normal power limiting. Plug in, check the adaptor and use the OEM performance profile.
• Low GPU utilisation with one or two saturated CPU threads: this points towards a CPU or game-engine limit, where reducing resolution may not help much.
• Stutter only on the first run after a driver or game update: shader compilation is a possible cause. Repeat the same section before drawing conclusions.
• Regular, rhythmic stutter: check capture software, RGB utilities, monitoring tools, antivirus scans and cloud sync in Task Manager.
• HDR looks wrong while SDR is fine: recalibrate HDR and test the game's native HDR separately from Auto HDR.
• Only one game is affected: check that title's own support information, verify its files and remove mods before changing Windows globally.
• Every 3D game is struggling: return to driver state, GPU selection, power, thermals, hardware stability and Windows update history.

The Windows 11 "gaming tweaks" we'd leave alone

Optimisation videos and one-click scripts often recommend changes simply because they're technically possible to make. A setting should earn its place by solving a problem you've actually measured — not because a script offered to flip it for you.

Disabling Windows Security, Memory Integrity or VBS as standard practice

Memory Integrity uses virtualisation-based security to protect critical kernel code, and it may already be enabled by default on a compatible Windows 11 installation.

Switching it off reduces that protection. Whatever the performance effect happens to be on your particular hardware and workload, that isn't a blanket reason to tell every gamer to disable it.

Leave Windows Security, Secure Boot, Memory Integrity and VBS at their supported defaults. Microsoft explains the security technology in its Memory Integrity and VBS documentation.

If you've measured a repeatable CPU-bound problem and understand exactly what protection you're trading away, a temporary controlled A/B test can tell you whether it matters on that particular machine. Re-enable the protection afterwards.

Don't disable Microsoft Defender because a video promises lower latency. A claim isn't the same thing as evidence.

Turning off Windows Update indefinitely

Security updates matter on a gaming PC signed into game launchers, browsers, voice chat and online services. Use active hours and scheduled restarts rather than freezing the machine on an old build.

If a specific, documented update causes a regression, pause briefly while you investigate or roll back that one update with a clear plan to restore normal updating. Don't turn a temporary troubleshooting step into a permanent "never update again" policy.

Blanket service-disabling and "debloat" scripts

Opaque scripts and giant service checklists can break Xbox services, Microsoft Store dependencies, audio, networking, Bluetooth, anti-cheat software, updates and recovery features — and whoever wrote the script is unlikely to have tested it against your exact Windows build, motherboard, peripherals and applications.

Remove an application you understand through Settings → Apps → Installed apps. Diagnose a genuine service conflict with a clean boot instead.

Registry, timer, HPET and process-priority hacks

Claims about "zero latency" registry packs, forced timer resolution, HPET modes and permanent Realtime process priority often lack repeatable modern testing.

They can introduce new stutter, starve audio or input handling, and make genuine troubleshooting considerably harder afterwards. Game engines, anti-cheat systems and current Windows builds simply don't all behave alike.

Unless a game or hardware manufacturer documents a specific change for a specific fault, leave these settings alone.

Disabling the page file

The page file isn't simply slow redundant RAM waiting to be deleted for a performance win.

Windows and applications use virtual memory in ways that affect commit limits and crash-dump behaviour. Disabling it can turn a memory spike into an application failure without improving normal gaming performance.

Leave it system managed unless you're solving a specialised problem with evidence and understand the memory requirements involved.

Forcing Ultimate Performance and a 100% minimum processor state

These settings can increase idle clock speeds, heat and fan noise without improving a GPU-limited game. On a laptop, extra heat can even result in lower sustained boost clocks later in a long gaming session.

Balanced is a sensible default. Move to Best performance or an OEM performance profile when you've actually established that the machine is being power-limited.

Windows 11 Home or Pro for a gaming PC?

Windows 11 Pro doesn't provide inherently higher gaming FPS than Windows 11 Home. Both editions use the same core DirectX graphics platform and include the gaming features covered in this guide.

Choose Pro when its non-gaming capabilities are what you actually need — for example BitLocker management, hosting Remote Desktop sessions, Group Policy, Hyper-V or business administration features.

A streamer, developer or home-lab user might genuinely need one of those features. An ordinary gaming-only PC generally doesn't need Pro for performance.

If you're setting up a new PC and still need to choose an edition, you can compare the available Windows editions after deciding which non-gaming features you'll actually use.

A ten-minute Windows 11 gaming checklist

That baseline is worth more than twenty unrecorded tweaks. If performance changes later, it gives you something real to compare against.

Frequently asked questions

Should Game Mode be on in Windows 11?

Yes, leave it on by default. It's intended to make gaming sessions more consistent and reduce interruptions, not guarantee extra FPS. Test it off only when diagnosing a repeatable conflict in a specific game or capture setup.

Should I enable Hardware-accelerated GPU scheduling?

Start with whatever Windows defaults to. HAGS can behave differently across games, GPUs and drivers. If you're investigating repeatable stutter or frame-pacing trouble, benchmark the same scene with HAGS on and off and restart Windows between tests.

Why is my 144 Hz, 165 Hz or 240 Hz monitor running at 60 Hz?

Check Settings → System → Display → Advanced display and select the intended rate on the correct monitor. If it isn't listed, check the cable, port, monitor input mode, GPU driver and the game's own display settings. Try disabling Dynamic Refresh Rate temporarily if a game appears capped below the selected maximum.

Does DirectStorage automatically make every game faster?

No. The game has to implement it, and the benefit is mainly faster loading or asset streaming on suitable storage. There is no global switch, and it won't increase FPS in unsupported games.

Does Auto HDR reduce gaming performance?

Any performance cost is game- and hardware-specific. Auto HDR is primarily an image-quality feature. Enable it because a compatible SDR game looks genuinely better on a capable, calibrated HDR display, not because you're expecting more frames.

Is Windows 11 Pro faster than Home for gaming?

No inherent gaming-performance advantage comes from Pro. Both editions share the same core gaming and graphics platform. Choose Pro only if you need its additional security, virtualisation, remote-access or management features.

Should I disable Memory Integrity for more FPS?

Not as a general gaming tweak. It provides kernel-level protection and its performance effect varies by system and workload. Only run a controlled temporary test if you've measured a specific CPU-bound problem and understand the protection you're giving up. Otherwise, leave it enabled.
