A gaming PC can start feeling slow or unstable over time. Games may take longer to load, stutter during gameplay, or struggle to run smoothly even when the hardware was good enough before.
I have faced this myself and found that the problem was not always the hardware. Updating drivers, closing unnecessary apps, changing Windows settings, and adjusting game graphics helped improve the experience.
In this blog post, I will show you the practical ways to optimize your PC’s gaming performance. Let’s start.
Quick Takeaways on How to Optimize PC Gaming Performance
- Update your graphics drivers and Windows regularly.
- Close unnecessary apps and turn on Windows gaming features.
- Adjust demanding in-game graphics settings to improve performance.
- Keep your PC cool and install games on an SSD when possible.
- Upgrade RAM, GPU, or CPU if software and settings changes are not enough.
What Affects PC Gaming Performance?
Several parts of your gaming PC and its software can affect how well games run.
- GPU has a major effect on FPS and graphics quality.
- CPU handles game calculations and other tasks.
- RAM helps your PC keep game data and other programs available while you play.
- Your storage drive can also affect loading times, especially if you are using an older hard drive.
High temperatures can reduce performance when the CPU or GPU slows itself down to prevent overheating.
Windows settings, background apps, graphics settings, and outdated drivers can also affect gaming performance. This means you may be able to improve your gaming experience without buying new hardware.
How to Optimize Your PC’s Gaming Performance?
There are a bunch of different ways through which you can boost the performance of your gaming PC. The details of these ways are given below:
Update Your Graphics Drivers
Your graphics driver helps Windows and your GPU work properly with games. NVIDIA, AMD, and Intel regularly release driver updates that can improve game compatibility and performance.
Check your GPU manufacturer’s software or website for the latest driver. If you recently installed a new graphics card, installing its latest driver is especially important.
Update Windows
Keeping Windows updated can also help with gaming performance. Updates can include bug fixes, security improvements, and changes that improve compatibility with games and hardware.
Open Settings > Windows Update and check for available updates.
Restart your PC after installing important updates if Windows asks you to do so.
Updating the operating system in this way is one of the basic ways of optimizing your Windows for gaming. It gives your PC the latest fixes and improvements for better compatibility and stability while gaming.
Close Unnecessary Background Apps
Programs running in the background use system resources that could otherwise be available to your game. This can be more noticeable on PCs with limited RAM or older CPUs.
Before starting a game, close apps you do not need. This can include web browsers, launchers, video editing software, and other programs using a lot of CPU or RAM.
You can also check Task Manager by pressing Ctrl + Shift + Esc. Look at the CPU, Memory, and GPU columns to see which programs are using the most resources.
Turn On Windows Gaming Features
Windows includes several features that can help your PC prioritize gaming and improve how games use your hardware.
Turn On Game Mode
Game Mode gives games more system resources by reducing some background activity.
Go to Settings > Gaming > Game Mode and turn it on.
Set Graphics Performance for Individual Games
Windows 10 lets you choose which GPU and performance preference a specific game should use. This can be useful if your PC has more than one GPU.
Go to Settings > System > Display > Graphics settings.
Under Choose an app to set preference.
Then, add your game and select Options.
If your PC has a dedicated GPU, you can choose High performance to use it for that game.
Change Windows Power Settings
Windows can limit power use to improve battery life on some PCs. This can also affect performance during gaming.
On a desktop, or when gaming on a plugged-in laptop, you can use a higher performance power mode. Go to Settings > System > Power & battery and check the available power mode options.
Keep in mind that higher performance settings can use more electricity and produce more heat. On laptops, they can also reduce battery life.
Note: These Power mode options are available in Windows 11. Windows 10 uses different power settings.
Optimize In-Game Graphics Settings
You can often improve FPS by changing a few demanding graphics settings. You do not need to set everything to Low. Start with the options that have the biggest impact on performance.
- Lower Resolution: A lower resolution gives your GPU fewer pixels to render, which can increase FPS. If a game struggles at 1440p, try 1080p.
- Reduce Shadow Quality: Shadows can use a lot of GPU power. Try lowering them from Ultra to High or Medium before changing other settings.
- Lower Ray Tracing: Ray tracing adds realistic lighting and reflections but can greatly reduce FPS. Lower it or turn it off if you need more performance.
- Adjust Anti-Aliasing: Anti-aliasing smooths rough edges but can affect performance. Try a less demanding option if you need extra FPS.
- Reduce Ambient Occlusion: This adds extra shading to objects and surfaces. Lowering or disabling it can provide some extra performance.
- Adjust View Distance: A higher view distance makes distant objects visible but puts more load on your PC. Lower it if you are struggling in large open-world games.
- Manage Texture Quality: Textures affect how detailed surfaces look and use your GPU’s VRAM. Keep them on High if your GPU has enough VRAM, or lower them if you notice stuttering or texture-loading problems.
Use DLSS, FSR, or Other Upscaling Features
Many modern games include upscaling technologies such as NVIDIA DLSS and AMD FSR. These features render the game at a lower internal resolution and then upscale the image to your selected output resolution.
This can increase FPS while keeping the image sharper than simply lowering the resolution.
If your game supports one of these features, try the Quality mode first. If you still need more performance, you can try Balanced or Performance.
The exact options depend on your GPU and the game.
Improve Your PC’s Cooling
Heat can affect gaming performance. When a CPU or GPU gets too hot, it may reduce its speed to control its temperature.
Make sure your PC has good airflow and that its fans are working properly. Clean dust from the fans, vents, and other cooling components when needed.
Having a CPU cooler can help a lot. If you’re considering buying a cooler, make sure to read my 360mm AIO CPU cooler review. After reading this, you can decide whether this cooler is the right choice for your PC’s cooling needs.
For laptops, avoid using them on beds or other soft surfaces that can block the vents. A hard, flat surface allows air to move more freely.
Free Up Storage Space
Keeping some free space on your storage drive can help Windows and other programs work normally. A nearly full drive can also make it harder to manage files and install updates.
Remove games, apps, and files you no longer need. You can also use Windows’ built-in storage tools to remove temporary files.
You do not need to keep your entire drive empty, but avoid letting it remain almost completely full.
Install Games on an SSD
An SSD can make games load much faster than a traditional hard drive. It can reduce loading times and may also help with texture and asset loading in some games.
However, moving a game from an HDD to an SSD does not automatically increase your average FPS by a large amount. The GPU and CPU usually have a much bigger effect on FPS.
If you still use an HDD for gaming, installing your frequently played games on an SSD is a useful upgrade.
Upgrade Your PC Hardware
Software changes cannot fix every performance problem. If your hardware is too old or weak for the games you want to play, a gaming PC upgrade regarding its components may be necessary.
Add More RAM
Having more RAM can help if your PC regularly runs out of available memory while gaming.
For modern gaming, 16 GB of RAM is a common starting point. Moving from 8 GB to 16 GB can help reduce slowdowns and stuttering in games that need more memory.
If you already have enough RAM for your games, adding more may not provide a major FPS increase.
As a beginner, upgrading RAM can be difficult and confusing. In that case, I strongly recommend you go through my guide on “How to Upgrade RAM for Gaming on PC?” This guide breaks down everything you need to know in simple words so that you can make the upgrade easily.
Upgrade the GPU
The GPU is one of the most important components for gaming performance. If your graphics card cannot maintain the FPS you want at your preferred resolution and settings, upgrading it can make a major difference.
A stronger GPU is especially useful if you want to play at higher resolutions or use demanding features such as ray tracing.
Before buying one, make sure your power supply, case, motherboard, and other components can support the new GPU.
Upgrade the CPU
The CPU can also limit gaming performance, especially in games that handle large numbers of characters, physics calculations, or complex game worlds.
If your GPU is not being fully used while your CPU is consistently near its limit, the CPU may be holding back performance.
A CPU upgrade can help improve FPS and reduce CPU-related stuttering. Keep in mind that picking the right CPU depends on your motherboard and current platform. So, make sure to read my guide on how to find the motherboard model on PC in order to know what type of CPU you should get.
Try Advanced GPU Tweaks
If you have already tried the basic changes, you can look at more advanced GPU settings.
For example, NVIDIA and AMD software provide additional graphics and performance options. You can adjust settings such as power preferences, shader cache options, and frame rate limits.
You can also use tools such as MSI Afterburner to monitor GPU usage, temperatures, clock speeds, and FPS.
Advanced tweaking should be done carefully. Changing GPU voltage or clock speeds without understanding the settings can cause crashes or instability. For most gamers, Windows and in-game settings are enough.
Final Words
You can boost PC gaming performance without immediately buying new hardware. Start with simple changes such as updating your graphics drivers, closing background apps, enabling Windows gaming features, and lowering demanding graphics settings.
Upscaling features such as DLSS and FSR can also help increase FPS. If your PC still struggles after these changes, consider upgrading components such as RAM, the GPU, or CPU based on what is limiting your performance.
