Few things are more frustrating for a PC gamer than a game that runs smoothly one moment and suddenly starts stuttering or losing FPS.
FPS drops can happen because of overheating, outdated drivers, background applications, insufficient RAM, high graphics settings, storage problems, or hardware limitations.
The good news is that many FPS problems can be diagnosed and improved without immediately upgrading your PC.
What Causes FPS Drops?
Before changing settings, it helps to understand the possible causes.
Common reasons include:
- High CPU usage
- High GPU temperatures
- Outdated graphics drivers
- Insufficient RAM
- Limited VRAM
- Background applications
- Overly demanding graphics settings
- Thermal throttling
- Nearly full storage
- Incorrect power settings
- Game optimization issues
The first step should always be identifying what is actually causing the problem.
1. Check Your FPS and Hardware Usage
Start by monitoring your PC while the game is running.
Pay attention to:
GPU usage
If the GPU is consistently close to full usage, your graphics card may be the main performance limitation.
CPU usage
If CPU usage is extremely high while GPU usage remains relatively low, your processor may be limiting the game.
RAM usage
If almost all available RAM is being used, background applications or insufficient memory may be contributing to stuttering.
GPU temperature
High temperatures can cause a GPU to reduce its operating speed.
Monitoring these numbers can help you avoid making unnecessary changes.
2. Update Your Graphics Driver
Graphics drivers are responsible for communication between your operating system, games, and GPU.
An outdated or problematic driver can cause:
- FPS drops
- Crashes
- Graphical glitches
- Compatibility problems
- Stuttering
Install the latest stable driver available for your graphics card from the official manufacturer.
After updating, restart your computer and test the game again.
3. Lower Graphics Settings
If your GPU is struggling, lowering graphics settings is one of the easiest solutions.
Start with settings that can have a significant performance impact:
- Ray tracing
- Shadows
- Reflections
- Volumetric effects
- Ambient occlusion
- View distance
- Hair or particle effects
You don’t necessarily need to set everything to Low.
Try reducing only the most demanding options while keeping textures and other visual settings at a level your GPU can handle.
4. Reduce Ray Tracing
Ray tracing can produce impressive lighting and reflections, but it can also place a substantial workload on your graphics card.
If you experience severe FPS drops after enabling ray tracing, try:
Ray Tracing → Off
or select a lower ray-tracing preset.
For many systems, disabling ray tracing can provide a noticeable improvement in performance.
5. Check Your Temperatures
If a game starts smoothly but becomes slower after 20–30 minutes, temperature may be the problem.
Check your:
- CPU temperature
- GPU temperature
- Fan speed
- Case airflow
Dust buildup can restrict airflow and increase temperatures.
On laptops, make sure the cooling vents aren’t blocked by a bed, blanket, or other soft surface.
If thermal throttling is occurring, improving cooling may provide a bigger benefit than changing Windows settings.
6. Close Background Applications
Background applications can consume CPU, RAM, GPU resources, and disk activity.
Before launching a demanding game, close applications you don’t need.
Examples include:
- Large browser sessions
- Video editing software
- Download managers
- Unnecessary launchers
- Screen recording applications
- Resource-heavy utilities
You can use Task Manager to identify applications consuming significant resources.
Press:
Ctrl + Shift + Esc
Then check the Processes section.
7. Enable Game Mode in Windows 11
Windows 11 includes Game Mode.
You can find it at:
Settings → Gaming → Game Mode
Turn Game Mode on and restart your game.
It is designed to prioritize gaming activity and reduce unnecessary background interference.
8. Use the Correct GPU
Gaming laptops often have both integrated graphics and a dedicated GPU.
If your game accidentally uses integrated graphics, performance can be significantly lower.
Go to:
Settings → System → Display → Graphics
Find your game and select:
High performance
This tells Windows to use the high-performance graphics processor when supported.
9. Check Your RAM
Modern games can use a considerable amount of system memory.
If your PC has limited RAM and several applications are open simultaneously, you may experience:
- Stuttering
- Long loading times
- Texture loading problems
- FPS drops
Close unnecessary applications before gaming.
If your system regularly runs out of physical memory, a RAM upgrade may be worth considering.
10. Check Your Storage Drive
A game installed on a slow or heavily used storage drive may experience longer loading times and occasional asset-streaming problems.
An SSD is generally preferable for modern games.
Also check how much free space remains on your system drive.
If the drive is nearly full, remove unnecessary files or uninstall applications you no longer use.
11. Check the Power Mode
On laptops especially, Windows power settings can affect gaming performance.
Go to:
Settings → System → Power & battery
When maximum performance is more important than battery life, select:
Best performance
Remember that high-performance modes can increase power consumption and heat.
For laptops, gaming while connected to the charger is usually preferable when maximum performance is required.
12. Don’t Automatically Use the Highest Preset
A common mistake is selecting:
Ultra / Extreme
and expecting the game to run perfectly.
Ultra settings are often designed for powerful hardware and can have a relatively small visual advantage compared with High settings.
Try:
High
first.
Then increase individual settings if your system has enough performance headroom.
13. Use Upscaling When Available
Modern games may support technologies such as:
- NVIDIA DLSS
- AMD FSR
- Intel XeSS
These technologies can render the game internally at a lower resolution and reconstruct the image to improve performance.
Depending on the game and hardware, an upscaling mode such as Quality can provide a useful performance improvement while maintaining good image quality.
14. Check Your FPS Limit
Some games include an FPS limiter.
If your game is unexpectedly locked to a low frame rate, check:
Game Settings → Display / Graphics → FPS Limit
Also check your monitor’s refresh rate in Windows.
For example, if you own a 144 Hz monitor but Windows is configured for 60 Hz, you may not be getting the display experience you expected.
15. Watch for Game-Specific Problems
Sometimes the problem isn’t your PC.
A newly released game may have:
- Shader compilation stutter
- Driver compatibility problems
- Poor optimization
- Memory leaks
- Server-related issues
- Bugs
Check the game’s official patch notes and community reports before changing advanced system settings.
If many players are experiencing the same problem, a developer update may eventually provide the real solution.
Final Thoughts
FPS drops don’t always mean that your PC needs an upgrade.
Start by identifying the bottleneck.
Check GPU and CPU usage, temperatures, RAM consumption, background processes, and graphics settings before spending money on new hardware.
For most players, the best troubleshooting order is:
- Check temperatures and hardware usage.
- Update GPU drivers.
- Close unnecessary background applications.
- Lower demanding graphics settings.
- Disable ray tracing if necessary.
- Enable Game Mode.
- Make sure the game uses the dedicated GPU.
- Check RAM and storage.
- Try an appropriate upscaling mode.
- Check for game-specific performance problems.
Once you know what is limiting your system, you can make targeted changes instead of randomly changing settings.
Gamesteller Quick Tip
Don’t judge performance only by average FPS.
Pay attention to stuttering and frame-time consistency as well. A game running at a stable 60 FPS can feel smoother than one jumping between 45 and 90 FPS.
