How Much Does Your CPU Affect FPS: CPU Influence on FPS

If you’re a gamer, you’ve probably heard the term “FPS” thrown around a lot. It stands for “Frames Per Second,” and it’s a crucial metric that determines how smooth and enjoyable your gaming experience will be. While your graphics card (GPU) plays a significant role in achieving high FPS, your CPU (Central Processing Unit) also plays a crucial part. In this article, we’ll dive deep into how much your CPU affects FPS in gaming.

Understanding the Basics

Before we get into the nitty-gritty details, let’s establish some fundamental concepts:

What is FPS?

FPS, or Frames Per Second, measures how many individual images (frames) your computer can generate and display on your screen every second. A higher FPS means smoother gameplay.


Your GPU is primarily responsible for rendering and processing the visuals in a game, while your CPU handles various game-related calculations and tasks. Both components work together to deliver an optimal gaming experience.

Now, let’s explore the ways in which your CPU influences your FPS.

CPU and Game Performance

Your CPU’s impact on game performance can be broken down into several key aspects:

1. Game Physics and AI

Modern games often feature complex physics simulations and artificial intelligence (AI). Your CPU plays a pivotal role in calculating and managing these aspects. When your CPU struggles to keep up, you may experience slowdowns or reduced FPS.

2. Game Logic and World Simulation

In open-world games, the CPU is responsible for managing the game world and all its elements. This includes tracking the movements of NPCs, handling quest logic, and maintaining in-game events. A powerful CPU ensures these processes run smoothly, maintaining a stable FPS.

3. Multiplayer Gaming

Online multiplayer games require real-time communication with game servers and other players. Your CPU’s ability to handle network tasks can affect your overall gaming experience. A faster CPU can reduce latency and ensure a more responsive online gaming experience.

4. Background Tasks

Your CPU doesn’t work exclusively for the game you’re playing; it also manages various background processes like your operating system and other applications. A faster CPU can handle these tasks more efficiently, leaving more processing power for your game, resulting in higher FPS.

CPU Requirements for Different Games

The CPU requirements for games can vary significantly depending on the title and its level of complexity. Here’s a breakdown of how different types of games can be affected by your CPU:

1. Esports and Competitive Games

Games like Fortnite, Counter-Strike: Global Offensive (CS: GO), and League of Legends prioritize high frame rates for competitive play. A mid-range CPU can handle these games well, ensuring you achieve the desired FPS for a competitive edge.

2. Triple-A Titles

Triple-A titles with stunning graphics, extensive open worlds, and intricate gameplay mechanics demand more CPU power. To enjoy these games at their best, a high-end CPU is recommended.

3. Simulation and Strategy Games

Simulation and strategy games, such as The Sims, Civilization, or Total War, often involve complex calculations and AI routines. These games benefit greatly from a powerful CPU to maintain smooth gameplay.

4. Older Games

Older games with less demanding graphics can run well on older or budget CPUs. However, a modern CPU can still improve their performance by ensuring stable FPS and reducing load times.

Triple-A TitlesHigh-end CPU
Simulation and Strategy GamesPowerful CPU
Older GamesModern CPU for stability

CPU Bottlenecks

A CPU bottleneck occurs when your CPU can’t keep up with your GPU’s capabilities. This situation can limit your FPS, even if you have a high-end graphics card. It’s essential to balance your CPU and GPU to avoid bottlenecks. Here’s how it works:

1. Low-End CPU with High-End GPU

If you pair a high-end GPU with a low-end CPU, your CPU may struggle to process game logic and AI quickly enough. This can result in a lower FPS than expected, even though your GPU is capable of more.

2. CPU-Intensive Games

Games that rely heavily on CPU processing, such as strategy games or MMOs, are more likely to experience CPU bottlenecks. In these cases, upgrading to a more powerful CPU can significantly improve your FPS.

CPU-Intensive GamesImproved FPS by upgrading to a more powerful CPU

Overclocking and CPU Performance

Overclocking your CPU can be an effective way to boost gaming performance, but it comes with risks and limitations:

1. Increased FPS

Overclocking can increase your CPU’s clock speed, allowing it to handle game-related tasks more quickly. This can result in higher FPS in some games.

2. Risk of Instability

Overclocking carries the risk of making your CPU unstable or overheating, which can lead to crashes or permanent damage. It’s essential to proceed with caution and monitor temperatures.

3. Diminishing Returns

Not all games benefit equally from overclocking. Some titles may see a substantial performance boost, while others may show minimal improvement. It’s essential to research and test each game individually.

Upgrading Your CPU

If you find that your CPU is holding back your gaming experience, you may consider upgrading. Here are some factors to consider:

1. Compatibility

Ensure your new CPU is compatible with your motherboard. Different CPUs use various socket types, so make sure they match.

2. Budget

Consider your budget when upgrading. High-end CPUs can be expensive, so balance your CPU choice with your GPU and other components to maximize performance within your budget.

3. Future-Proofing

Investing in a powerful CPU can future-proof your gaming setup, ensuring it can handle upcoming game releases and software updates for years to come.


Your CPU plays a significant role in determining your gaming FPS, especially in CPU-intensive games and scenarios. While a powerful GPU is essential for eye-catching visuals, a capable CPU ensures that the overall gaming experience remains smooth and enjoyable. Balancing your CPU and GPU, overclocking cautiously, and considering an upgrade when necessary can help you get the most out of your gaming rig. So, the next time you’re exploring a vast open world or competing in an esports tournament, remember that your CPU is right there with you, striving to deliver those buttery-smooth FPS that make your gaming adventures truly epic.
