Optimize Windows 11 for gaming: 10 useful settings
The internet is full of guides that promise spectacular gains by disabling half of Windows' services. The reality is more moderate: on a healthy machine, Windows 11 is already properly configured for gaming. However, a few settings are left in a sub-optimal state by default, and those are worth fixing.
Here are the ten points we systematically check in our workshop before a machine leaves. None require dubious third-party software, and none pose a risk to stability.
Settings that have a measurable effect
1. Enable the XMP or EXPO memory profile
This is by far the most cost-effective setting, and the one most often forgotten. By default, a motherboard runs RAM at a safety frequency much lower than what is printed on the sticks. You paid for fast memory, and it is running in slow motion.
Enter the BIOS at startup (usually the Del key), look for the XMP option on Intel platforms or EXPO on AMD, select profile 1, and save. Then check in the Task Manager, Performance tab, that the displayed frequency matches the one advertised by the manufacturer of the sticks.
The effect is clear in CPU-limited games: simulations, strategy games, and open-world titles loaded with assets.
2. Set the power mode to Best performance
Go to Settings > System > Power & battery > Power mode. On a desktop PC, there is no reason to stay in balanced mode: it introduces delays in the processor's frequency ramp-up, which results in micro-stuttering.
3. Enable hardware-accelerated GPU scheduling
In System > Display > Graphics > Change default graphics settings, turn on Hardware-accelerated GPU scheduling. It reduces display latency and is a prerequisite for some image generation technologies. A restart is required.
4. Check your screen's refresh rate
A classic error: a 144 or 165 Hz monitor left at 60 Hz by Windows. Go to Display > Advanced display settings and select the maximum value offered. Also, verify that your cable is up to the task: an old HDMI cable may limit the frequency or resolution.
5. Enable VRR and optimized windowed mode
Still in the graphics settings, enable Variable refresh rate and Optimizations for windowed games. The former reduces screen tearing on G-Sync or FreeSync compatible monitors. The latter significantly improves latency for games launched in borderless window mode, which is the default for many recent titles.
System hygiene settings
6. Clean up startup apps
Ctrl + Shift + Esc, Startup apps tab. Disable everything that doesn't need to launch with Windows: game launchers, sync clients, peripheral utilities. Each consumes memory and, more importantly, disk access at startup.
A special note on launchers: Steam, Epic, Battle.net, and others have no reason to run permanently. Launch them when you play.
7. Keep graphics drivers up to date, but do it properly
Download drivers from the GPU manufacturer's website rather than via Windows Update, which is often one or two versions behind. So-called "Game Ready" drivers usually come out a few days before major releases and fix specific issues.
If a driver update causes instability, roll back to the previous version rather than piling up hotfixes. The DDU utility allows you to completely uninstall a driver before reinstalling.
8. Leave free space on the system SSD
An NVMe SSD that is more than 90% full will see its write performance drop significantly. Aim for at least 15 to 20% free space on the system drive. If your games are overflowing, add a second SSD rather than saturating the first—it's also more convenient if you need to reinstall Windows.
Also, verify that the DirectStorage feature is not hindered: it requires an NVMe SSD and up-to-date drivers to work in compatible games.
9. Monitor temperatures rather than settings
Many performance losses attributed to Windows are actually thermal limitations. Install HWiNFO or HWMonitor and see what happens after twenty minutes of gaming.
| Component | Acceptable load temperature | Watch out above |
|---|---|---|
| Processor | 60 to 80 °C | 90 °C |
| Graphics card | 60 to 78 °C | 85 °C |
| NVMe SSD | 40 to 60 °C | 70 °C |
If the values are drifting, the problem is physical: case airflow, dust in the radiators, old thermal paste, or an undersized cooler. No software setting will compensate for that.
10. Disable pointer precision for shooters
In Devices > Mouse > Additional mouse settings > Pointer Options, uncheck Enhance pointer precision. This option applies variable acceleration that makes aiming unpredictable. Instead, adjust the sensitivity directly in your mouse software.
What is best avoided
A few practices circulate widely and provide no benefit, or even cause problems:
- All-in-one optimization software. They disable services at random, sometimes break Windows Update or Search, and their gains are not measurable.
- Disabling the page file. Even with 32 GB of RAM, some games need it and will crash without it.
- "Cleaned" registries. No proven benefit, a real risk of breaking an application.
- Massively disabling Windows services. The gains are marginal, and the side effects are numerous and difficult to diagnose weeks later.
Going further
If, after these adjustments, performance remains below your expectations, the problem is likely no longer software-based. The most common hardware causes are a processor that bottlenecks the graphics card, 8 GB of RAM that has become too little, or memory installed in single-channel instead of dual-channel—check that your two sticks are in the slots recommended by the motherboard manual.
