Does CPU Affect FPS? [Definitive Answer 2024]

Written By Farhan Max

Do you want to build a new computer but are stuck on a tight budget? As a result, you are confused about whether you should go for a good CPU or GPU.

If this is the case, you’ve come to the right place.

I am a professional gamer and have been playing games for the last ten years or more. I know how much higher FPS matters in competitive gaming. In this article, you will see the role of A CPU in FPS.

How does a CPU Affect FPS?

The CPU is the brain of the computer. It’s in charge of all the instructions that need to be processed. It basically is the powerhouse of a computer because the CPU performs every instruction and task. Yes, CPU does have an impact on frame rates. Not drastically, but yes, it has.

Frames per second, or FPS, is a measurement of how fast graphics appear on a computer screen. In video capture, playback, and video games, frames per second (FPS) is a measurement that evaluates display device performance.

In simple words, fps is how fast the contents on the screen refresh every second. It is the most demandable thing in the gaming and graphical department.

When you’re playing a game, your CPU communicates with the various components of your computer. It will give instructions to the GPU and feed data to it to render textures and sceneries.

Therefore, if your CPU isn’t quick enough to keep up with and instruct the GPU, you will receive poor FPS, your games will lag, and you will have a horrible experience overall.

Having said that, the single-core performance affects FPS mostly. And single-threaded goodness comes with the IPC of the CPU.

RAM also affects a game’s fps big time. Insufficient system memory causes stutters and frame time inconsistency.

Here is how CPU can affect frame rates: 

  • At the time of starting a game, the CPU looks for the storage for the relevant files and resources, then loads them into RAM for speedier access.
  • The CPU must process the appropriate instructions and computations quickly enough for the GPU to render each new picture.
  • The CPU takes your input and calculates your motions and locations every time you use a keyboard, mouse, or another input device. As a result, it instructs the GPU on what to display on the screen.

So, yes, a faster CPU can help a lot with the other components that need more immediate instructions to obtain better frame rates.

Apart from that, check the CPU temperature whether it is overheating and causing any performance issues.

How to Improve FPS in Games

Now, the concern arises about how you can improve frame rates in games.

I am dividing this part into two sections. Hardware tweak and software tweak. Both of which will emphasize optimizing the CPU for gaming.

Here I’m listing these two sections below:

Implementing New Components

This section is for those willing to spend money and want to upgrade their system.

Here is how you can improve fps by upgrading hardware:

  • Upgrade or adding a new GPU to your system can boost frame rates significantly. Newer GPUs have a higher memory count and bandwidth. Those can easily push frame rates to a very demandable number.
  • Upgrade your existing processor to a newer one can boost frame rates. Getting a processor with a higher core count can give you an extra edge. However, there is a minimal difference in frame rates between a 6-core CPU and an 8-core CPU. But bumping up from a 4-core CPU to a 6 or 8-core CPU will give you a better overall performance.
  • For ram, you can either upgrade your existing ram kits or install a second ram if you have a single stick of ram. Overclock your ram(if needed) to make sure you get the full speed from your ram. Getting a total of 16 gigabytes of dual-channel ram can easily give you your desired frame rates if you have a compatible system.
  • A proper cooling system can boost your system’s performance which will end up in better frame rates in games. As you game on your system and it is not cooled correctly, then overheating can lower CPU performance and can even damage your system. So having a decent cooling system is very important.

Tweaking Existing Components

This section is for the people who don’t want to upgrade their system but want the most out of it.

You can also try optimizing the GPU. So that, you can extract the last bit of performance out of your system.

Here is how you can improve fps by tweaking softwares:

  • Enable Game Modes in Windows 10 or 11 to have an optimized experience. That will help your system to push more frame rates.
  • Lower your resolution if you don’t have a robust system. By lowering the resolution, your system needs to push fewer pixels on the screen, which will result in better frame rates.
  • Update your drivers. Older drivers don’t have the optimization of the latest games or softwares. Updated drivers can help you to get better frame rates.
  • Perform a disk cleanup to clean the system junks. These junks may often cause performance drops. Cleaning those junks can boost frame rates.
  • Overclock your CPU and GPU. Overclocking will let you get the most out of your system. You can quickly notice the difference in frame rates after overclocking your CPU and GPU.

Final Opinion

So, at the end of the article, you know the factors which may affect frame rates in games. And as the main topic of this article asked, yes, CPU can affect frames rates. If it is not as powerful as the other system components or is an older system, that may not run the game properly.

Hopefully, you’ve learned everything there is to know about in-game FPS. And which factors may affect frame rates.

I hope I have answered all the questions regarding frame rates. Use this information to get better frame rates in games.
