How to Optimize Windows 11 for Gaming

Learning how to optimize Windows 11 for gaming is the cheapest upgrade you can make, because most of the settings that slow games down are already on your PC, waiting to be changed. You do not need a new graphics card to get smoother play. Turning on Game Mode, updating your drivers, choosing the right power plan, and clearing the background programs that steal CPU and RAM can raise your frame rate, cut stuttering, and reduce input lag, all for free.

Windows 11 was designed with gaming in mind. It includes Game Mode, Auto HDR, DirectStorage, and hardware-accelerated GPU scheduling, but many of those features are off by default, or they only help when your drivers and game settings match. This guide works through them in the order that matters most, starting with a quick baseline so you can see what actually helped, then moving through Windows settings, drivers, background apps, in-game settings, and storage. Follow the steps in order, test after each big change, and keep the ones that help your games.

A warning before you start: avoid so-called game booster programs that promise huge gains in one click. Most of them do the same things this guide does, but they also install extra software, change settings you cannot see, and sometimes add ads. The built-in Windows tools below do the job safely, and you can undo every change in this guide in a few clicks.

Step 1: Measure Your Baseline First

Before you change anything, measure how your game runs now, or you will never know what helped. Pick one game you play often, note its resolution and graphics settings, and play for ten minutes in a busy scene. Press Windows key + G to open the Xbox Game Bar, click Performance, and pin the small performance window so you can watch frames per second, CPU use, GPU use, and RAM use while you play. Write those numbers down, or take a screenshot with Windows key + Alt + Print Screen.

Also note how the game feels, not just the numbers. Is there stuttering when you turn quickly, long loading times, or a delay between moving the mouse and the game responding? Those symptoms point to different causes: stuttering often means the CPU or RAM is overloaded, long loads often mean a slow drive, and input lag often means VSync or a background program is in the way. Keep your notes, because you will compare them after the changes below.

If your PC does not meet the minimum requirements for the game, no amount of tuning will fix it, so check the game’s store page first. Our guide to how to check your Windows version and PC specs shows you how to find your processor, graphics card, and RAM in a minute, so you can compare them with the game’s requirements before you spend time tuning.

Step 2: Turn On Game Mode and Graphics Settings

Game Mode is the first setting to check. Open Settings, go to Gaming, then Game Mode, and turn it on. Game Mode tells Windows to prioritise your game over background work: it stops Windows Update from installing drivers in the middle of a match, pauses some notifications, and gives the game a more stable share of CPU and GPU time. It helps most on laptops and mid-range PCs, where background programs compete with the game for resources.

Next, set your graphics preferences for each game. In Settings, go to System, then Display, then Graphics. Click the game you want to tune, or browse for its executable file if it is not listed, click Options, and choose High performance. This tells Windows to use your dedicated graphics card instead of integrated graphics, which is a common cause of low frame rates on laptops with two graphics chips. Repeat this for every game you play regularly, because the setting is per game, not global.

While you are in the graphics settings, check the advanced options on the same page. If your PC supports it, turn on Hardware-accelerated GPU scheduling and restart your PC. This lets the graphics card manage its own memory more efficiently and can reduce latency in some games. If a game runs worse after you turn it on, turn it off again: it helps some systems and hurts a few, so test it with your baseline numbers.

Auto HDR is another Windows 11 feature worth testing if you have an HDR display. It adds HDR lighting to games that were not designed for it, and it is found in Settings, under Gaming, then HDR, or under System, then Display, then HDR, depending on your Windows version. Turn it on only if your monitor supports HDR, and turn it off again if colours look washed out, because not every game benefits from it.

Step 3: Update Your Graphics Drivers Safely

Outdated graphics drivers are the single most common cause of poor gaming performance, crashes, and new games that will not start at all. Graphics card makers release new drivers for almost every major game, and those drivers often include performance fixes that can raise frame rates by 10 percent or more in that game alone. Check for a new driver before you change anything else in this guide.

Get drivers only from the maker of your graphics card: NVIDIA, AMD, or Intel. The safest way is to use the maker’s own app, such as the NVIDIA App or AMD Software, which checks your card model and installs the matching driver. You can also download the driver by hand from the maker’s website, for example the NVIDIA driver download page, and choose your exact card model. Do not use third-party driver updater programs, which often install the wrong driver or bundle extra software. Our guide to how to update Windows 11 drivers safely walks through the whole process, including how to roll back if a new driver causes problems.

After you install a new graphics driver, restart your PC, even if it does not ask you to, and test the same game and scene you used for your baseline. Also update your chipset drivers from your laptop or motherboard maker’s website, because those drivers control how the processor, memory, and graphics card talk to each other. Keep Windows Update running as well, because it delivers DirectX and other gaming components, but let the graphics card maker, not Windows Update, provide the main graphics driver.

Step 4: Choose the Right Power Plan and Performance Settings

On a laptop, the power plan can cut your frame rate in half without you realising it. Open Settings, go to System, then Power and battery, and set Power mode to Best performance before you play. On a desktop, the same setting is found under System, then Power. Best performance lets the processor run at full speed, while Balanced and Best power efficiency slow it down to save energy, which is fine for browsing but not for gaming.

If your laptop has a performance mode in the maker’s own app, such as a gaming or turbo mode, turn that on too, and plug the laptop into the charger. Most gaming laptops limit performance sharply on battery, no matter what Windows says, so always play plugged in when you want full speed. Also check that the laptop is not overheating: a hot laptop slows itself down to protect its parts, so use it on a hard, flat surface, clean the vents, and check the fan is not blocked by a case or a soft surface.

In Windows, also turn off the visual effects you do not need while gaming. Search for Adjust the appearance and performance of Windows, open it, and choose Adjust for best performance, then turn back on only Smooth edges of screen fonts and Show thumbnails instead of icons if you want them. This frees a small amount of CPU and memory, and it matters most on older PCs. You can also turn off Transparency effects in Settings, under Personalization, then Colors, for a small extra gain.

Step 5: Free Up RAM and CPU Before You Play

Games need RAM and CPU time, and every browser tab, chat app, and background program takes a share. Before you start a game, close your browser, or at least close the tabs you do not need, because a browser with many tabs can use several gigabytes of RAM on its own. Close cloud sync apps, video editors, and other heavy programs, and pause any downloads or updates, because a download in the background can cause stuttering in online games.

Check what is using your PC with Task Manager. Press Ctrl + Shift + Esc, click Processes, and sort by CPU or Memory to see the biggest users. If a program you do not need is using a lot of resources, close it from Task Manager. Our guides to how to free up RAM on Windows 11 and how to reduce high CPU usage on Windows 11 explain these checks in detail, including which processes are safe to close and which belong to Windows itself.

Also review the programs that start with Windows. Many of them stay running in the background from the moment you log in, even if you never use them. Our guide to how to check which programs start with Windows shows you how to disable the ones you do not need at startup, which frees RAM for games and makes Windows start faster as well. Keep your antivirus, audio, and graphics software enabled, and disable only programs you recognise and do not need every day.

Step 6: Turn Off Notifications and Background Apps

Notifications are a small distraction that can cause a big stutter when they pop up during a game. Turn on Do not disturb before you play: click the date and time in the taskbar, or open Settings, go to System, then Notifications, and turn on Do not disturb. Game Mode already silences some notifications, but Do not disturb makes sure nothing else interrupts you. You can set it to turn on automatically at certain times, or turn it off again when you finish playing.

Next, stop apps you do not use from running in the background. Open Settings, go to Apps, then Installed apps, click the three dots next to an app you do not need in the background, choose Advanced options, and set Background apps permissions to Never. Do this for social media, shopping, and other apps that do not need to update while you play. Keep background access on for your game launcher, your chat app if you use it in game, and your antivirus.

Also pause OneDrive and other cloud sync tools while you play, because syncing large files can use CPU, disk, and internet bandwidth at the same time. Right-click the OneDrive icon in the system tray and choose Pause syncing for two hours. When you finish playing, resume syncing so your files stay backed up. The same applies to game launchers: let them finish any downloads and updates before you start playing, because a game that updates in the background will stutter and lag.

Step 7: Optimise Your In-Game Settings

Windows settings help, but the biggest frame rate gains usually come from the game’s own settings menu. Start with resolution: playing at your monitor’s native resolution looks best, but dropping one step, for example from 1440p to 1080p, can raise frame rates a lot on a mid-range graphics card. If your game offers a resolution scale or render scale slider, try 85 or 90 percent instead of 100 percent: the image stays sharp, but the graphics card has less work to do.

Next, lower the settings that cost the most performance for the least visible benefit. Shadows, reflections, and ambient occlusion are usually the most expensive, so set those to Medium or Low first. Anti-aliasing smooths jagged edges, but it is also expensive, so try a lighter option, or use your graphics card’s upscaling feature instead. Many modern games offer NVIDIA DLSS, AMD FSR, or Intel XeSS, which render the game at a lower resolution and upscale it with clever software. Turning one of those on, in Quality mode, is often the best single change you can make, because it can raise frame rates by 30 percent or more with only a small loss in image quality.

Turn off VSync if you notice input lag, because VSync waits for the monitor before showing each frame, which adds delay. If you see screen tearing without VSync, turn on your monitor’s adaptive sync instead, such as G-Sync or FreeSync, and cap your frame rate a few frames below your monitor’s refresh rate in the game’s settings or in your graphics card app. A frame rate cap also stops the graphics card from working harder than it needs to, which keeps temperatures and fan noise down.

Finally, check the game’s display mode. Fullscreen usually performs better than borderless windowed, because Windows does not have to draw the desktop at the same time. Some games also have a reduced latency or low latency mode in their settings, or in the NVIDIA or AMD app: turn that on for competitive games where every millisecond counts, and leave it off for slow, story-driven games where it makes no difference.

Step 8: Keep Windows, Storage, and Your SSD Healthy

Games load faster and stutter less when Windows and your drive are healthy. Make sure Windows Update is up to date, because updates include DirectX, security fixes, and gaming improvements, but schedule updates for a time when you are not playing, so they do not start in the middle of a match. Also make sure your game is installed on an SSD, not an old hard drive, if you have both. An SSD can cut loading times from minutes to seconds, and it reduces the stuttering that happens when a game loads new areas from disk.

Free up space on the drive where your games live. Games need free space for updates, shader caches, and temporary files, and a drive that is more than 90 percent full slows down. Uninstall games you no longer play, and move large files to another drive. Our guide to how to free up disk space on Windows 11 the safe way shows you how to clean up safely without deleting anything important, and our roundup of the best free system cleaners for Windows in 2026 compares tools that can help with the job.

Do not defragment an SSD: Windows optimises SSDs automatically, and defragmenting them wears them out without helping. For a hard drive, Windows runs its own optimisation on a schedule, so leave that alone too. Instead, check your drive health once in a while in Settings, under System, then Storage, then Advanced storage settings, then Disks and volumes, and look for warnings. A failing drive causes crashes and long loads, and no settings change will fix it.

Fixing Common Gaming Problems on Windows 11

If a game stutters even after the steps above, check the temperature. Download a free monitoring tool, or watch the performance window in the Xbox Game Bar, and look at the CPU and GPU temperatures while you play. Temperatures above 90 degrees Celsius usually mean the PC is slowing itself down to avoid damage. Clean the dust from the vents and fans, make sure the PC has room to breathe, and on a laptop, raise the back slightly so air can flow underneath. A cooling pad can help a laptop, but cleaning the vents helps more.

If a game crashes to the desktop, update the graphics driver first, then verify the game files in your game launcher, because a corrupted file is a common cause. Steam, the Epic Games Store, and the Xbox app all have a Verify or Repair option for installed games. If the crash continues, turn off overlays one by one: the Discord overlay, the Xbox Game Bar, and your graphics card’s overlay can all conflict with some games. Turn them back on one at a time to find the culprit.

If online games lag, the problem is usually your connection, not your PC. Use a wired Ethernet cable instead of Wi-Fi when you can, because Wi-Fi adds latency and drops packets. If you must use Wi-Fi, move closer to the router, use the 5 GHz network, and stop other devices from streaming video or downloading large files while you play. Restart your router once in a while, and test your connection speed on a clean device to see whether the problem is your PC or your internet service.

Frequently Asked Questions

Does Game Mode really help on Windows 11?

Yes, especially on laptops and mid-range PCs. Game Mode gives your game priority over background work and stops updates and notifications from interrupting play. The gain is usually small, a few frames per second and steadier frame times, but it is free and it costs nothing to turn on.

Should I use High performance power mode all the time?

No. Use Best performance only while you play, because it uses more power, makes the fan louder, and drains a laptop battery faster. Switch back to Balanced when you finish, so your PC runs cooler and quieter for everyday work.

What is the best free way to increase FPS?

Update your graphics drivers, turn on your game’s upscaling feature such as DLSS or FSR, and lower shadows and reflections first. Those three changes usually give the biggest gain for free. Closing background apps and choosing High performance graphics for the game are the next best steps.

Will more RAM make my games run better?

It can, if you do not have enough now. Most modern games need at least 16 GB of RAM, and running a game with only 8 GB can cause stuttering when Windows has to use the drive as extra memory. If you already have 16 GB or more, adding more RAM will not raise your frame rate much, and a faster graphics card or SSD will help more.

Is it safe to turn off background apps and startup programs?

Yes, as long as you only turn off programs you recognise and do not need every day. Keep your antivirus, audio, and graphics software running, and do not disable anything from Microsoft or Windows itself. Every change in this guide can be undone in the same settings page, so you can turn a program back on if something stops working.

Conclusion

To optimize Windows 11 for gaming, start with the free settings that matter most: turn on Game Mode, set each game to High performance graphics, update your drivers, choose Best performance power mode, and close the background apps that steal RAM and CPU. Then tune the game’s own settings, using upscaling and lower shadows first, and keep your games on an SSD with plenty of free space. Test your frame rate after each change, keep the settings that help, and undo the ones that do not. With those steps, most PCs play noticeably smoother without spending anything on new hardware, and you will know exactly which change made the difference.
