Laptop Gaming Performance Issues: Causes and Solutions


What are the possible causes and solutions for a sudden drop in laptop performance while gaming?

I have a laptop that used to run fortnite smoothly at 100-140fps, but recently it started to lag and stutter at 30fps. The fans also became very loud and the laptop felt hot. I suspect that dust might be clogging the vents, so I ordered some compressed air to clean it. However, I am not sure if that is the only problem or if there are other factors affecting the performance. Could you please advise me on how to diagnose and fix this issue? Thank you.


Laptop gaming can be a fun and immersive experience, but it can also be frustrating when your laptop suddenly slows down and starts to overheat. This can affect your gameplay, your battery life, and your laptop’s longevity. In this article, we will explore some of the common causes and solutions for this problem, and how to prevent it from happening again.

Cause 1: Dust accumulation

One of the most likely reasons for your laptop’s poor performance is dust accumulation. Dust can clog the vents and fans of your laptop, reducing the airflow and cooling efficiency. This can cause your laptop to overheat, which can throttle the CPU and GPU performance, resulting in lower frame rates and lagging. Dust can also damage the internal components of your laptop, such as the motherboard, the hard drive, and the RAM.

Solution 1: Clean your laptop regularly

The best way to prevent dust from affecting your laptop is to clean it regularly. You can use a can of compressed air to blow out the dust from the vents and fans, or use a soft brush or a cotton swab to gently wipe the dust away. You should also avoid placing your laptop on dusty or dirty surfaces, such as carpets, beds, or couches. Instead, use a hard and flat surface, such as a desk or a table, or use a cooling pad or a laptop stand to elevate your laptop and improve the airflow.

Cause 2: Background processes

Another possible cause for your laptop’s poor performance is background processes. These are programs or applications that run in the background, consuming your CPU, RAM, and disk resources. Some of these processes are essential for your laptop’s operation, such as the operating system, the antivirus, and the drivers. However, some of these processes are unnecessary or unwanted, such as malware, bloatware, or auto-updates. These processes can interfere with your gaming performance, causing stuttering, freezing, or crashing.

Solution 2: Optimize your laptop settings

The best way to prevent background processes from affecting your laptop is to optimize your laptop settings. You can use the task manager to monitor and close the processes that are using too much of your resources, or use a third-party software to optimize your laptop for gaming, such as Razer Cortex or Game Booster. You should also scan your laptop for malware and viruses, and uninstall or disable any programs or features that you don’t need or use, such as bloatware, auto-updates, or notifications.

Cause 3: Outdated or corrupted drivers

Another possible cause for your laptop’s poor performance is outdated or corrupted drivers. Drivers are software that allow your laptop to communicate with the hardware, such as the CPU, the GPU, the sound card, and the keyboard. If your drivers are outdated or corrupted, they can cause compatibility issues, errors, or glitches, affecting your gaming performance and quality.

Solution 3: Update or reinstall your drivers

The best way to prevent drivers from affecting your laptop is to update or reinstall them. You can use the device manager to check the status of your drivers, and update them if they are outdated or have a yellow exclamation mark. You can also use a third-party software to update your drivers automatically, such as Driver Booster or Driver Easy. Alternatively, you can reinstall your drivers by uninstalling them from the device manager, and downloading and installing them from the official website of your laptop manufacturer or hardware vendor.


In conclusion, there are many possible causes and solutions for a sudden drop in laptop performance while gaming. By following the tips and steps mentioned above, you can improve your laptop’s performance, and enjoy a smooth and satisfying gaming experience. However, if none of these solutions work, or if your laptop is too old or damaged, you may need to consider upgrading or replacing your laptop with a newer or better model. Thank you for reading this article, and happy gaming!
