Why Is My Gaming PC Stuttering? 10 Common Causes and How to Fix Them
Lennon Byatt
There's nothing more frustrating than launching your favourite game only to experience random stuttering, frame drops or hitching. Even if your average FPS looks good, inconsistent performance can make games feel sluggish and ruin the experience.
The good news is that gaming stutter is often caused by a handful of common issues, and many of them are easy to fix.
In this guide, we'll explain the most common reasons why your gaming PC stutters and show you how to improve gaming performance.

What Is Stuttering?
Unlike low FPS, stuttering happens when your frame times become inconsistent.
For example, your game may run at 120 FPS most of the time but suddenly pause for a fraction of a second before continuing.
This creates noticeable hitching, even though your FPS counter still looks high.
1. Your Graphics Drivers Need Updating
Outdated graphics drivers are one of the most common causes of gaming performance issues.
New driver releases often include:
- Performance improvements
- Bug fixes
- Game-specific optimisations
- Stability updates
If you've recently installed a new game, check for the latest GPU drivers before troubleshooting anything else.

2. Your CPU Is Running at 100%
Modern games rely heavily on the processor.
If your CPU is constantly maxed out, it may struggle to prepare frames quickly enough, leading to stuttering.
Signs include:
- High CPU usage
- Low GPU usage
- Poor minimum FPS
- Frame pacing issues

For modern AAA titles, 32GB of RAM is becoming the recommended amount
3. You Don't Have Enough RAM
Running out of system memory forces Windows to use your storage drive as virtual memory, which is much slower.
Symptoms include:
- Random freezes
- Long loading times
- Texture pop-in
- Browser slowing down while gaming
For modern AAA titles, 32GB of RAM is becoming the recommended amount.

4. Your SSD Is Nearly Full
Solid State Drives need free space to maintain peak performance.
If your SSD is almost full, game loading and asset streaming may become less efficient.
Aim to leave at least 15–20% free space where possible.

Let the Card "Bed In"
Some users report that coil whine becomes less noticeable after several weeks of regular gaming.
While this isn't guaranteed, it can happen as components settle over time.
Should You Return a Graphics Card?
If coil whine is extremely loud and disruptive, it's worth contacting the retailer to discuss your options.
However, because coil whine is generally considered a normal characteristic of modern graphics cards, it may not always qualify as a manufacturing fault.
If your graphics card performs normally in every other way, keeping it is often the best option.
Best Sim Racing Setup for Beginners: Start With the Essentials
You don’t need a full cockpit immediately. A well‑chosen beginner setup helps you develop skills faster and keeps costs under control.
1. Steering Wheel and Pedals (Top Priority)
Your wheel and pedals are the most important part of any sim racing rig. Force feedback allows you to feel grip changes, kerbs, and steering resistance—crucial for learning car control.
Beginner tip: Focus on force feedback quality rather than raw power.

5. Your PC Is Overheating
When temperatures become too high, your CPU or GPU may reduce clock speeds to protect themselves.
This process, known as thermal throttling, often causes sudden frame drops.
Monitor your temperatures using trusted hardware monitoring software and ensure your PC has good airflow.
6. Too Many Background Applications
Programs running in the background can consume valuable CPU cycles and memory.
Before gaming:
- Close web browsers
- Pause downloads
- Exit RGB software you don't need
- Disable unnecessary startup applications

Performance will vary depending on drivers, game updates and graphics settings.
7. Your Power Plan Is Limiting Performance
Windows may be using a balanced power profile.
Switching to High Performance (or the appropriate manufacturer-recommended profile) can help prevent unnecessary CPU downclocking during gameplay.
Ultra settings aren't always worth the performance cost
8. Your Game Is Installed on an HDD
Older mechanical hard drives struggle with modern games that stream large amounts of data.
Installing games on an NVMe SSD can significantly reduce:
- Loading times
- Texture streaming issues
- Open-world stutter
9. Your Graphics Settings Are Too High
Ultra settings aren't always worth the performance cost.
Try reducing:
- Ray tracing
- Shadow quality
- Volumetric effects
- Ambient occlusion
These settings often have a large impact on frame times.
10. Your Hardware Needs an Upgrade
If your gaming PC is several years old, newer games may simply be pushing it beyond its limits.
Upgrading your graphics card, processor or memory can dramatically improve both average FPS and frame consistency.

How to Check What's Causing Stutter
The easiest way to identify the problem is to monitor your system while gaming.
Keep an eye on:
- CPU usage
- GPU usage
- RAM usage
- GPU temperature
- CPU temperature
- SSD capacity
Identifying which component is reaching its limit makes troubleshooting much easier.
Frequently Asked Questions
Why does my game stutter even with high FPS?
High average FPS doesn't guarantee smooth gameplay. Inconsistent frame times, background processes or hardware bottlenecks can all cause stuttering.
Can RAM cause stuttering?
Yes. Insufficient RAM or slow memory can lead to hitching, particularly in open-world games or when multitasking.
Will an SSD fix stuttering?
If stuttering is caused by slow asset streaming or a mechanical hard drive, upgrading to an NVMe SSD can help improve consistency.
Final Verdict
Gaming stutter can have many different causes, but most problems can be traced back to outdated drivers, overheating, insufficient RAM, slow storage or ageing hardware.
By checking each of these areas one by one, you can often eliminate stuttering without replacing your entire system.
If an upgrade is needed, AWD-IT offers a wide range of gaming PCs and components designed to deliver smoother gameplay in today's most demanding titles.
