One thing that we need to watch out for, when building computers, is bottlenecks. The definition of bottleneck in the world of PC means when the capacity of a computer system is limited by a single component. Imagine the neck of a bottle slowing down the water flow. That’s kind of what it is like for a PC. The smartest thing to do before buying computer parts is to take some time and research on different hardwares to see if it would bottleneck other parts. The part that is in charge of increasing frame rates is probably the graphics card. But, the main factor that affects the frame rates on your screen is the GPU and CPU. Most modern games are dependent on them. However, not all the credit goes to those two components. It is actually a mix of power that all the parts of the PC are able to push out. So, what are the computer parts that affect fps?

The computer parts that affect frame rates are GPU, CPU, graphics card, memory and motherboard. When playing a game, it also depends on the graphics and resolution settings, and how well the game code is optimized and developed for graphic performance.

In this post, we will be sharing some details on what computer parts affect frame rates. We will also be breaking down each component and explain about how each computer part affects fps. If this is your first time learning holistically about computers, I’ll be doing my best to provide some simplified explanation and hopefully it can help all of us understand computer vocabulary better!

What Computer Parts Affect FPS?

It is important to keep in mind that a chain is only as strong as its weakest link. What I meant is, the key is to find parts with similar caliber to achieve the best performance. Graphics card isn’t the only component that is important when it comes to boosting frame rates. In fact, there are a number of factors that contribute to frame rate or fps performance.

Here are a list of things that plays a role in processing frame rates:

- System hardware, which includes:

  • GPU (Graphic Processing Unit)
  • CPU (Central Processing Unit)
  • Graphics card
  • Storage
  • RAM
  • Motherboard

- The graphics and resolution settings within the game, application or program.

- How well the game code is optimized and developed for graphics performance.

What Does Each Of These Computer Parts Do?

All of those components listed above play a part in processing and rendering images for your monitor. A lot of people think that the graphics card is the only thing that renders image but that isn't true. Every component has to work together for that, but of course having a graphics card would help. Unless you have a weak CPU or weak GPU that isn't able process something too big. My point is that every component works with each other, so it is important to do your research on each component of your PC and see if they work well together. Anyways, let's find out the details of what each component is responsible of.

CPU (Central Processing Unit)

The CPU is in charge of processing simulations, game logic, boundary and collisions, AI decisions, and the animation of every object on screen. It determines your maximum frame rate and it also sends instructions to your graphics card and GPU. Keep in mine that a weak CPU can limit your frame rates no matter how good your graphics card is.

GPU (Graphic Processing Unit)

The CPU sends information to the GPU. The GPU then takes the instructions given by the CPU and it calculates the geometry, texturing, lighting, shading, and every pixel on the screen. It renders the image of every single object you see on screen. Only the objects are calculated by the GPU. All the actual logic happens on the CPU.


Using an SSD (solid-state drive) can help out loading time and reduce stuttering. Basically, using an SSD can help the game to retrieve data quicker. So, if your storage is slow, it might cause some stuttering.

RAM (Random Access Memory)

The CPU takes the data that it needs for the game out of the storage and then it stores it in the RAM. Taking data out of the RAM is much faster as it can transfer up to 20GB! Having a faster RAM can get you at least about 10 more fps and it also reduces stutters.


The motherboard affects performance too. A better quality motherboard can deliver more power to components in a more efficient way. It can allow your CPU and graphics card to run quicker.

The Process of Rendering Images

Now that we have each component explained, here's the process of rendering an image, laid out for us to understand things better:

1. The computer's CPU and GPU has to work between each frame. The CPU sends information and instructions from programs, applications and games to the graphics card.

2. The graphics card then processes the instructions that it received.

3. Next, it renders the image and sends it to the monitor for display.

A weak CPU will not be able to achieve high fps and a weak GPU means you won't get high frame rates. Arduous games require both CPU and GPU to work together, because you need a GPU to achieve great frame rates and a smart CPU that works fast enough. Another way to achieve good frame rates is to find the right balance with the game's graphics and resolution. I would recommend you to check out the settings of the game and tweak it to your preference.

Other Factors That Can Help The System Work Better

It is very important to have a cooling system. Cooling down your PC can help components run smoother. We should never let our PC or laptop over heat because it will affect your computer's performance. Modern graphics cards perform better when it is cooler, so make sure you have a good cooling system for your console.

What If I Want To Improve Frame Rates Without Spending Money?

There are ways to improve your computer's fps without upgrading your PC's components. I can't guarantee that it will work for your computer. But, if you have tried this method that I am about to share and it didn't work for you, that could mean that it's time to upgrade your component as it might be too old to process a big game, application or program.

Here are some helpful tips for your reference:

1. Reduce resolution

The resolution you play at affects the gaming performance most. Drop the resolution to 1920p x 1080p. That way you can reduce the number of pixels and improve the performance. Yes, the game will look more pixelated, but you may or can be able to run the game!

2. Update graphics card drivers

First, figure out what video card you own. Go on Windows and open the device manager, that is how you can check the display adapter. Next, find and download the latest drivers from any computer company's website of your choice and follow the instructions given by it.

3. Change the game settings

Lower the game's video settings can help the game run smoother. Keep an eye on settings like shadow quality as that can affect the game's performance. Look at other settings as well and tweak it to your preference. The key is to experiment with different settings that can help your computer load programs or images better.

4. Use a PC optimization software

There are PC optimization softwares that can help clear out other processes that are not needed during the time where you are focused on one program or game. Unneeded processes might ruin game performance, so it is best to clear out other processes. The good thing about Windows is that it includes some built-in optimization tools. So if you're a Windows user, try that out.

Final Thoughts

In conclusion, every part of your computer does affect the frame rate. This is because every component has to work efficiently with each other in a smooth process, in order to achieve a quality frame rates. As mentioned above, it takes the power of all the components to push and boost your frame rates. If one component is not as up to date as the rest, it might impact the frame rate. That means the game or the program that you are running might work slower.

Make sure to keep your computer parts up to date and save yourself some trouble from slow loadings screens and bad frame rates! I think the idea of investing on upgrading a computer can only benefit us, either for work or just for fun. That is all of the information I have on today's topic! I hope the details were portioned into understandable concepts. Thank you for reading and I hope this has been a good read for you. Stay crazy and game on!
