How to Fix CPU Bottleneck

A CPU bottleneck is an annoying problem to have. It reduces the efficiency of your whole system because a single core on a computer handles everything going on in it.

If that one goes out, then you’re left with less power for other tasks or just waiting longer than desired until another component fails so they can replace instead!

A few ways may help fix this issue: upgrading slower components such as DDR2 RAM (which can take up 1GB per second) towards faster GDDR5 modules at 5 GB/s each helps reduce load times significantly. 

Purchasing more cores- meaning having dual or quad-core processors will allow multiple processes to run simultaneously without interference.

Different Ways To Fix CPU Bottleneck

CPU or GPU can be challenging to fix if you don’t know what you’re doing. All the basics are just tweaks, but balancing everything out takes some extra work- Let’s see how that works!

1. Shoot Up The Resolution Of The Game

It is an easy way to fix a CPU bottleneck. For example, suppose your graphics card has more horsepower than what’s available in our onboard chipset. 

Then, it will have trouble processing all those calculations necessary for high-res games at higher resolutions like 1440p and 4k displays.

Whatever you do, make sure that both components share similar hardware requirements because only by doing so will no bottlenecks arise during gameplay!

2. Close Inessential Background Processes

Closing unnecessary background processes can sometimes help in CPU bottlenecks. 

It’ll make sure of a higher FPS and give you back some quality time with your friends!

To do so, go to Task Manager and close all the unessential stuff that’s bogging down performance, like browser toolbars or Reading List apps. But don’t forget about essential system processes too; otherwise, there will be no option, but system failure–so choose wisely before hitting.

3. See If Overclocking The Ram Works

When you’re looking for a performance boost, don’t just depend on one tool. The best way is by using both RAM and CPU in tandem with each other to find the Bottleneck slowing them down.

It can fix before they work against each other, causing further complications instead of improving things as much as possible!

4. Try Overclocking The CPU

Overclocking your computer’s processor can be a great way to fix sluggish performance. 

Setting the clock speed at a to overclock might help if you’re experiencing slowdowns.

But don’t go above what Intel or AMD recommends as too high of a setting could prevent booting up properly!

5. Lower CPU Dependent Settings

CPUs are complicated and confusing devices. Thankfully, we can simplify things by lowering the CPU-dependent settings, which will remove a lot of pressure from your computer’s processor!

What is a CPU Bottleneck?

You may have experienced a CPU bottleneck in your work before. For example, imagine if you were trying to pour water from an open bottle, and there was no cap on it at all.

 What would happen? After some time has passed with nothing happening (i.e., less liquid), the amount coming out will significantly decrease because gravity is also taking effect.

It happens because every second that goes by means another drop gets into those empty spaces below where we can see right now. 

It is because they’re filling up fast enough without our input, causing any more movement upwards.

Now let’s say instead of being done pouring continuously as this one situation above might be. Instead, we stop midstream whenever FPS drops.

All the data transfer to your computer causes a bottleneck for both processor and graphics card. If they can’t process it fast enough, these other system parts will become idle until you do something about this pesky problem!


The leading cause of a GPU bottleneck is the discrepancy in performance between your graphics card and processor. 

For example, you have an older 9th generation Intel Core i5-965 that will force you into experiencing frequent “CPU Threading” errors.

The primary cause for a CPU bottlenecking is learning the difference between games that use your computer’s graphics processing unit (GPU) and those where it mainly has to work with its processor.

 It will help you understand more about what causes bottlenecks in general, rather than just one type of game at a time!

Minecraft may be a simple game, but it does not hold up to Metro Exodus when it comes to graphics. But what happens in the background? 

Minecraft farms would visually only exist as blocky structures on your screen; however, there is so much going on behind them that requires processing power from your computer’s processor (CPU).

Which frequently takes more time than simply doing less destroying or building things with blocks like pieces of cake!

When you’re experiencing a problem with your computer, don’t just think about what kind of game it is. 

Instead, consider how far apart the performance on each component (CPU and GPU) is when trying to diagnose whether there’s an issue or not!

Can Bottleneck Damage Your PC?

There is no way to damage your computer through a bottleneck. A hot processor won’t kill your components, and it just makes the CPU or GPU run at 100%.

It proves that tests with high temperatures have minimal lifespan when comparing them against other factors such as regular use. 

We might only worry about this more than others if something is stuck inside our system, causing an obstruction.

All they need is some attention from time to time (like every two years), depending upon usage patterns!


The way to avoid a CPU bottleneck is by monitoring your processor and graphics card usage in games. 

For example, suppose you see that the number of times either one has completed calculations outweighs any other process. 

In that case, there’s probably an issue with how much load each system can handle before slowing down the gameplay or crashing altogether. 

If you are experiencing CPU bottlenecks in your workstation, the best solution is to upgrade or replace the computer. 

Some software solutions may be able to help reduce CPU usage and improve performance. But if these options don’t fix the problem for you, it’s time to go shopping!
