Computer lag can be a frustrating experience, especially for those who play games that interfere with productivity and overall performance. 

Table of Contents

The problem of PC lag can be caused by a number of factors, ranging from faulty hardware, poorly optimized software or even malware. 

In this article, we’ll explore why you’re lagging, how to solve PC lag and tips on how to fix this problem, ensuring better performance when gaming.

Identify Of PC Lag

Lag can be very detrimental to the usability of a PC, especially for gamers, whose high latency during games is detrimental to the performance of the game. 

But lag on your PC can appear in other ways, such as when you’re watching a video on your cell phone and the player starts buffering, even if your Internet connection is fine. 

In addition, another way of identifying lag is when simple applications take a long time to open right after you turn on your PC.

Here are some of the main factors that can contribute to system slowdown:

  • Running Programs: Many programs running simultaneously can overload the processor and RAM, resulting in slowness.
  • Outdated Hardware: Components such as the CPU, GPU, and RAM that are outdated or insufficient may not keep up with the demands of modern software.
  • Insufficient or Fragmented Storage: Full or fragmented hard drives can lead to longer loading times and overall slower performance.
  • Malware and Viruses: Malware infections can consume system resources and compromise the security and performance of your PC.
  • Outdated Drivers: Outdated or incompatible drivers can cause conflicts and slow down the system.
  • Overheating: Overheating components can lead to reduced performance as the system throttles speeds to prevent damage.
  • Software Settings: Inadequate software settings, including power and performance options, can negatively impact your PC’s speed.
  • Outdated Operating System: An outdated operating system may not be optimized for running newer software.
  • Startup Applications: Many applications configured to start automatically with the system can slow down startup time and overall performance.

But, what is lag on PC?

Lag refers to a noticeable delay between an action (such as clicking a mouse or pressing a key) and the corresponding response on your computer screen. It can manifest in various ways:

Input Lag

This occurs when there is a delay between your input (e.g., clicking a mouse button) and the action being executed on the screen. Input lag is often noticeable in games or when using graphic design software.

Display Lag

This refers to delays in the time it takes for the monitor to refresh and display new information. It can result in a delay between when an action occurs (like moving a character in a game) and when it appears on the screen.

Network Lag

In online gaming or video streaming, network lag (or latency) refers to delays in data transmission between your computer and the server. This can cause interruptions, buffering, or delays in gameplay.

Hardware Lag

This is caused by hardware limitations, such as insufficient RAM or an outdated graphics card, which struggle to keep up with the demands of running applications or games.

Software Lag

Poorly optimized software or background processes consuming too many resources can lead to lag. This can include applications running in the background that use up CPU or memory resources.

Identifying and addressing the specific cause of lag can significantly improve overall performance and user experience on your PC.

What is stuttering lag on PC and why It happens?

Be it online or offline, you probably dealt with stuttering while gaming at least once in your life.

Suddenly lag spikes and choppiness while moving in an open world game?Irregular delays? The problem not going away after a hardware upgrade?

Well, that’s stuttering lag; and it could happen not only on the PC, but also consoles.

Games with huge maps are prone to stutter, and that’s because of irregular delays between your GPU and display image.

Additionally, this is a hardware-related or software-related factor contributing to lag.

What is freezing lag on PC and why It happens?

Have you ever had your PC freezing in the middle of nowhere? Sometimes you’re not even gaming, just browsing the web, and then, freeze!

Sometimes, if you just let your PC rest for a few minutes, it comes back to life. However, at times, a hard reset is required.

The causes of freezing could be multiple: too many tabs open, overheating, and even viruses. This is also a hardware-related or software-related factor contributing to lag.

What is latency lag on PC and why It happens?

If you’re playing and your game starts lagging, the first thing you’ll do, probably, is to check your network connection. 

Latency lag is all about that: unstable connection, lag spikes or high ping.

This is a network-related cause of lag, your internet simply is not functioning the way it should. It also could be a long distance between you and game server.

Fortunately, ExitLag proves highly effective in resolving latency issues.

As time moves on in the gaming industry, developers will start to take advantage of more sophisticated hardware in order to make their new titles look and perform even better.

As a result, gamers will need to upgrade their PC if they want to keep up with the most recent releases.

If you’re dealing with any of the issues stated below, it might be a sign that an upgrade is in order:

  • Insufficient RAM or outdated hardware
  • Overheating issues and inadequate cooling
  • Incompatible or outdated graphics card

Insufficient RAM Or Outdated Hardware: Why Your PC Is Lagging

An issue that is most common in games that boast large, open areas, such as Fortnite and Grand Theft Auto is constant stuttering as you’re trying to simply walk around from one zone to another.

Since your computer doesn’t have enough resources (in this case, memory) to keep up with the game, you’ll start dealing with textures simply unloading, crashes or even a blue screen of death.

Overheating Issues And Inadequate Cooling on PC

Inadequate cooling is one of the most dangerous issues PC gamers could deal with, as it generally impacts not only the performance of their systems, but also the longevity of the hardware they’re equipped with.

Gamers need to make sure that they have the right cooling equipment that best matches the components and programs they’re going to use.

Those who wish on buying water coolers need to be absolutely certain that their radiators and AIO pumps are placed at the correct angle.

Keep in mind that sometimes simply cleaning your system and placing it in an area where it could receive better ventilation could also do wonders for you.

Incompatible Or Outdated Graphics Card

As stated previously, if gamers want their newest games to perform in a stable environment, they will need to make sure their PCs are up to the task.

With new technologies such as Ray Tracing making a big impact in how developers want their titles to be presented. Older cards, such as the GTX 1060, are starting to be cast aside, and as such, not being the standard anymore.

Gamers need to always keep an eye on the minimum and recommended specs to have an idea on which cards better suit their needs and wallets.

If you’re starting to deal with low FPS even while lowering the visuals and resolution, then it might be time for an upgrade.

The good news is that since the chip shortage has been getting better for the past couple of years, most PC components are starting to have more reasonable prices once again.

Background Processes And Resource-Intensive Programs

Often easy to miss, most gamers tend to download a bunch of programs that, while might be important, start draining the necessary resources their system needs the most while gaming.

Closing programs such as torrent trackers, gaming clients and other tools like Discord or even CurseForge could help you a lot.

Outdated Or Incompatible Software And Drivers: Why Your PC Is Lagging

A way most developers are trying to make sure their games run well enough on most systems nowadays is partnering up GPU developers to release drivers close to the launch of their titles.

Every time a new game is bound to release, make sure to check the control panel of your graphics card as it is bound to have a new driver update that will make sure the game will run well enough.

Why is my computer slow?

A slow computer can be caused by various factors, from running too many programs simultaneously, not enough RAM, a fragmented hard disk, malware, outdated drivers, overheating, old hardware and more. 

Picture this: you boot up your high-end PC excited for another night of intense gaming sessions, and then all of sudden things start taking too long to load, games start underperforming and even the most menial tasks make your computer freeze.

If this is happening constantly, then it is a sign that some software could be making your system struggle.

It is time to check out for:

  • Background processes and resource-intensive programs
  • Outdated or incompatible software and drivers

Playing with high ping is one of the most frustrating experiences gamers deal with whenever they’re jumping into a new match online.

You could have the best skills in the world and it would all be rendered useless if you have to deal with lag. Be sure to keep an eye open when dealing with these issues:

  • Slow internet connection or high latency
  • Network congestion or interference
  • Router or modem issues

Slow Internet Connection Or High Latency

If you’re playing a match and then all of a sudden your shots start missing, enemies keep teleporting away or if any interaction with someone else takes way longer than it should, you’re probably dealing with high ping.

The best thing to do in these situations is to always contact your ISP and make sure everything should be fine on their end. Sometimes they could be performing maintenance or undergoing a network stress test, which could be affecting all users, not just yourself.

Network Congestion Or Interference

If you live in a household where multiple people have access to the same network device, you’re bound to deal with some network traffic congestion sooner or later.

Whenever users start using intensive tasks such as watching something on streaming services, downloading programs or even playing another game, the overall quality of your bandwidth will decrease.

Some efficient methods to combat this could be simply turning off your Wi-Fi connection, so that you don’t have to compete for bandwidth against other users. Or limiting the speed per device connected to the network so that you could all still share the same internet access.

Router Or Modem Issues

A common issue with users that rely on Wi-Fi connection to use the internet is that they tend to not have a router strong enough to send wireless signal across their entire household, and as such have weaker signal strength.

Sometimes you could be even using a wired Ethernet cable, and while your modem says everything should be working correctly, your system might not be receiving any kind of connection.

Whenever this happens, it is recommended to turn off your router for about 10 minutes and then plug it back once again.

While this might sound of fashioned, you would be shocked with how many issues go away once you simply reset your hardware.
