Your Gaming PC Is BOTTLENECKED! – Here’s How To Fix It!

What Are CPU Bottleneck and GPU Bottleneck?

As a gamer, you may have come across the terms “CPU bottleneck” and “GPU bottleneck” while troubleshooting performance issues on your gaming PC. Understanding these bottlenecks can help you identify and resolve the root cause of any performance limitations you may be experiencing.

A CPU bottleneck occurs when the performance of your graphics card (GPU) is limited by the processing power of your central processing unit (CPU).

On the other hand, a GPU bottleneck happens when the CPU can handle more tasks than the GPU can process, resulting in the GPU not being fully utilized.

Why Does Bottleneck CPU GPU Happen?

There are several reasons why a CPU or GPU bottleneck can occur in your gaming PC:

  • The CPU or GPU may be outdated or underpowered compared to the other component.
  • The game you are playing may be more demanding on either the CPU or GPU, causing an imbalance in performance.
  • Inadequate cooling or improper overclocking settings can also lead to bottlenecks.

How to Fix CPU Bottleneck?

If you find that your gaming PC is experiencing a CPU bottleneck, here are some solutions to consider:

  1. Increase Game Resolution: By increasing the game resolution, you can shift some of the workload from the CPU to the GPU, potentially reducing the bottleneck.
  2. Close Unnecessary Background Processes: Closing unnecessary background processes and applications can free up CPU resources, allowing your gaming PC to allocate more power to the game.
  3. Lower In-game CPU-related Settings: Adjusting in-game settings that heavily rely on CPU processing, such as draw distance or physics simulations, can help alleviate the CPU bottleneck.
  4. Overclock CPU: If you have adequate cooling and a compatible CPU, overclocking can increase its clock speed, boosting overall performance and reducing the bottleneck.
  5. Overclock RAM: Increasing the speed of your RAM can also help improve CPU performance, especially in memory-intensive games.

How to Fix GPU Bottleneck?

If your gaming PC is suffering from a GPU bottleneck, here are some solutions to consider:

  1. Upgrade Your GPU: If your GPU is outdated or underpowered, upgrading to a more powerful model can help eliminate the bottleneck.
  2. Lower Game Resolution and Graphics Settings: Lowering the game resolution and graphics settings can reduce the workload on the GPU, allowing it to perform better.
  3. Update Graphics Drivers: Keeping your graphics drivers up to date ensures optimal performance and compatibility with the latest games.
  4. Optimize Game Settings: Some games offer specific settings to balance CPU and GPU usage. Adjusting these settings can help alleviate the GPU bottleneck.
  5. Monitor and Control Temperature: Ensuring proper cooling and monitoring GPU temperature can prevent thermal throttling and improve overall performance.


Identifying and addressing CPU and GPU bottlenecks is crucial for optimizing your gaming PC’s performance. By understanding the causes behind these bottlenecks and implementing the appropriate solutions, you can ensure a smoother and more enjoyable gaming experience.

Remember, every gaming PC is unique, and the solutions that work for one system may not be suitable for another. Experimenting with different settings and configurations will help you find the best solution for your specific hardware and gaming needs.
