Is your PC bottlenecking? Find out how to verify for efficiency issues

Fast Hyperlinks

In case you’re a PC gamer then likelihood is you’ve got heard of the time period bottleneck and are conscious that it is doable to have an issue together with your system whereby you are not getting the perfect efficiency out of it.




There are issues you are able to do to optimise your gaming PC and increase your FPS besides, the elements of your system might be limiting total efficiency.

It is due to this fact necessary to grasp what a bottleneck is, easy methods to verify to see in case you have a bottleneck in your system and easy methods to repair it. We’re right here to assist.



What’s a bottleneck?

In a gaming PC, a bottleneck occurs when one part is limiting the efficiency and capabilities of one other. That is usually right down to the utmost efficiency capabilities of the elements and their use.

Usually talking, there are two primary elements that may be impacted by a bottleneck – the CPU and the graphics card. Both one or the opposite of those two elements can create a bottleneck and forestall you from getting most efficiency from the opposite.

Over time you might effectively improve elements of your system and players are likely to decide to improve the GPU first as that is the best factor to alter. However in the event you do that with out additionally upgrading different elements then there might be an enormous distinction within the processing energy of the CPU and the GPU.

This downside would not essentially occur over time both. You possibly can actually have a bottleneck in a brand-new gaming PC if you have not purchased the proper elements. In case you paid out for a high-end CPU however purchased a less expensive graphics card to chop prices then you’ll have inadvertently created a bottleneck. Equally, in the event you spent all of your cash on a top-end GPU however a finances processor, you then’ve created a special subject. The secret’s stability.

Why bottlenecks occur

For PC players the perfect finish result’s a clean gaming expertise with excessive FPS.

Each the CPU and GPU are concerned within the creation of the gaming expertise. These two elements play a vital half within the rendering of the ultimate picture that you just see in your gaming monitor.

Despite the fact that you may not realise it, the central processing unit (CPU) is closely concerned within the graphical course of. It’s used to calculate issues like gameplay physics, sport audio, positional information and way more. It additionally performs an necessary half within the rendering course of – passing information to the graphics card to be rendered and displayed in your monitor.

The graphics card then handles issues just like the shaders, textures and different graphical information. Each elements need to work shortly collectively with a purpose to ship the perfect outcomes. In case you have a flagship GPU however a finances CPU then your CPU may not be capable to sustain and you have created a CPU bottleneck.

The graphics card on this state of affairs is rendering information and dealing more durable and sooner than the CPU can handle and so is remaining idle whereas it waits for the CPU to catch up. That is time wasted and a less-than-optimum expertise.

You want a stability of moderately matched {hardware} with a purpose to keep away from a bottleneck.

Apparently what you are doing also can have an effect on efficiency and the bottleneck. In case you’re taking part in fashionable video games at 4K with a high-end graphics card (just like the Nvidia RTX 3090 or 4090) then the GPU is doing many of the work, even with a high-end CPU within the system. Whereas taking part in at 1080p as a substitute can permit the CPU to be extra concerned.

Does your PC have a bottleneck?

In case you’re unsure whether or not your gaming PC has a bottleneck or not, fear not, as a result of there are methods to verify.

There are a number of completely different choices open to you. One easy one is to make use of a bottleneck calculator. That is a web-based software that means that you can enter your part checklist after which get ideas on whether or not any single part is inflicting you issues.

This is not an ideal resolution although, as it’s extremely generic and never based mostly on the specifics of your system.

The opposite extra correct technique to verify for a bottleneck is by monitoring the efficiency of your gaming PC whilst you’re utilizing it.

You need to use one thing just like the efficiency metrics accessible by way of Nvidia GeForce Expertise to observe efficiency in real-time. We have written about easy methods to activate this earlier than by way of improving FPS or utilizing Nvidia Reflex, however you can even use it to see how a lot your GPU and CPU are getting used whereas gaming and search for any bottlenecks.

One other various is to make use of MSI Afterburner. Obtain and run this free software on a second monitor and you may see your real-world efficiency whereas it is occurring.

If when doing this you see that your CPU is getting used way more than your graphics card then this would possibly point out a CPU bottleneck. Whereas a GPU bottleneck is indicated when the information goes the opposite manner.

If there’s solely a small distinction in efficiency, then it could be nothing to fret about. Some video games are additionally extra CPU intensive than others. So it is value maintaining that in thoughts.

If you do not have a spare monitor, don’t fret as a result of you can even set MSI Afterburner to observe and log efficiency.

To verify for a bottleneck this fashion observe these steps:

  1. Launch MSI Afterburner and click on on settings
  2. Then head over to the monitoring part
  3. Click on to pick your CPU and GPU beneath energetic {hardware} monitoring
  4. Then beneath the “{hardware} monitoring historical past” click on “log historical past to file”
  5. Click on apply

Then whereas MSI Afterburner is working, merely load up your favorite video games and play as you all the time do. Once you’ve been taking part in for some time (we would suggest a minimum of an hour) you may then verify your logs. They’re saved on this file – C:/Program Recordsdata (x86)/MSI Afterburner/HardwareMonitoring.hml.

Verify these logs to see if there are any giant variations in efficiency by way of how a lot your CPU or GPU is being utilised.

Find out how to repair bottlenecks

In case you assume you could have a bottleneck then the answer sadly entails upgrading your PC elements. You are in all probability prone to discover that an ageing CPU is the most definitely reason for your bottlenecks. You may presumably upgrade your CPU in some circumstances, however you would possibly want to contemplate updating your motherboard and different elements too.

There isn’t any simple resolution, however a bottleneck additionally is not essentially the top of the world. If efficiency is clean and also you’re getting good FPS then do not overly fear about it.

Alternatively, use this as an excuse to improve your gaming PC. Simply do not blame us.
