What Causes High CPU Usage in Opera GX

Understanding the root cause is the first step to fixing any problem. Opera GX uses your CPU for many tasks at the same time. Some of these tasks are necessary, while others are just wasting resources. Let us look at the main reasons your browser might be working too hard.

Too Many Open Tabs

Every tab you open uses memory and CPU power. Even if a tab is not active, it still runs in the background. If you have 30 or more tabs open, your CPU is working hard to keep them all alive. This is one of the biggest reasons why is Opera Gx using so much CPU. Each tab runs its own processes, and they all add up fast.

Think of it like having 30 apps open on your desktop at the same time. Your computer was not designed to handle that much at once. The more tabs you keep open, the more your CPU struggles to keep up.

Heavy Browser Extensions

Extensions add cool features to your browser, but they also use CPU power. Ad blockers, VPNs, and productivity tools all run in the background. Some extensions are poorly optimized and use way more resources than they should. If you have installed a lot of extensions, they could be the main reason your CPU usage is high.

Each time a page loads, your extensions run their code. This adds extra work for your processor. Over time, this builds up and causes noticeable slowdowns. Checking which extensions you actually need is a great first step.

Background Processes and Sync

Opera GX syncs your data across devices. It also runs background processes to check for updates and notifications. These processes use CPU power even when you are not actively using the browser. If you notice high CPU usage when Opera GX is minimized, background processes are likely the cause.

The browser also preloads pages and caches content to make browsing faster. While this improves speed, it also increases CPU usage. This trade-off between speed and performance is something every user should understand.

Outdated Browser Version

Running an old version of Opera GX can cause performance problems. Older versions may have bugs that cause high CPU usage. Updates often include performance improvements and bug fixes that address these issues. If you have not updated your browser in a while, this could be contributing to the problem.

How to Check What Is Using Your CPU

Before you start changing settings, you need to know what is actually causing the high CPU usage. Your operating system has built-in tools that show you exactly which processes are using the most resources.

Using Task Manager on Windows

Press Ctrl + Shift + Esc to open Task Manager. Click on the Processes tab and sort by CPU usage. You will see a list of all running processes and how much CPU each one is using. Look for Opera GX and any related processes at the top of the list.

You can also expand the Opera GX entry to see individual tabs and extensions. This helps you identify exactly which tab or extension is causing the problem. If one tab is using 30% of your CPU, you know exactly where to look.

Using Activity Monitor on Mac

If you are on a Mac, open Activity Monitor from your Applications folder. Go to the CPU tab and sort by percentage. Find Opera GX in the list and check its CPU usage. Just like on Windows, you can see individual processes and tabs that are using the most power.

How to Fix High CPU Usage in Opera GX

Now that you know what causes high CPU usage, let us fix it. These steps will help you reduce the load on your processor and make browsing smoother.

Use GX Control to Limit CPU Usage

Opera GX has a built-in feature called GX Control. This tool lets you set limits on how much CPU and RAM the browser can use. To access it, click the Opera GX menu and go to Settings. Then find the Performance section.

You will see sliders for CPU usage and RAM usage. Set the CPU limit to a percentage that works for your system. For example, if you set it to 50%, Opera GX will never use more than half of your processor. This is one of the easiest and most effective fixes for why is Opera Gx using so much CPU.

The GX Control feature is unique to Opera GX and sets it apart from other browsers. It gives you direct control over browser performance without needing third-party tools. If you have not tried it yet, this should be your first stop.

Close Unused Tabs and Extensions

This might sound simple, but it works. Close any tabs you are not actively using. Right-click on your tab bar and select “Close tabs to the right” to quickly clean up. For extensions, go to the Extensions menu and disable anything you do not need.

You do not have to uninstall extensions forever. You can simply turn them off when you are not using them. This frees up CPU resources and helps your browser run faster. Making this a habit will keep your system running smooth.

Clear Cache and Cookies

Over time, your browser accumulates cached data and cookies. While this data helps pages load faster, too much of it can slow things down. Clearing your cache can reduce CPU usage and fix performance issues.

Go to Settings and find the Privacy & Security section. Click on “Clear browsing data” and select Cached images and files. Choose a time range and confirm. This simple step can make a big difference in how your browser performs.

Regularly clearing your cache also helps with privacy and security. It removes old data that websites have stored on your computer. Aim to do this at least once a week for best results.

Disable Hardware Acceleration

Hardware acceleration uses your GPU to help render web pages. While this sounds helpful, it can sometimes cause high CPU usage. This is especially true on older systems or systems with limited GPU power.

To disable hardware acceleration, go to Settings and find the Advanced section. Look for System and toggle off “Use hardware acceleration when available.” Restart your browser and check if CPU usage improves.

Not everyone will need to do this. If you have a modern system with a dedicated GPU, hardware acceleration usually helps. But if your system is older or struggling, turning it off can reduce CPU load significantly.

Update Opera GX to the Latest Version

Browser updates fix bugs and improve performance. If you are running an older version of Opera GX, you might be experiencing issues that have already been fixed. Check for updates by going to Menu and selecting About Opera GX.

The browser will automatically check for updates and install them. Restart the browser after updating and see if your CPU usage improves. Keeping your browser up to date is one of the simplest ways to maintain good performance.

How Browser CPU Usage Affects Your Overall System

When Opera GX uses too much CPU, it affects your entire system. Other apps slow down, games lag, and your PC feels sluggish. Understanding this connection helps you see why managing browser CPU usage is so important.

The Ripple Effect on Other Applications

Your CPU has a limited amount of power. When Opera GX takes a large share, other programs get less. This means your word processor, video editor, or game all run slower. If you have ever tried to game while browsing and experienced lag, this is why.

High CPU usage from your browser can also cause your system to heat up. When your processor works hard, it generates more heat. This can lead to thermal throttling, where your CPU slows down to protect itself from overheating. Over time, this can reduce the lifespan of your components.

Using a quality cooling solution can help manage this heat. If you want to learn more about keeping your system cool, check out What Is The Best Cpu Cooler for expert recommendations.

Impact on Website Performance

High CPU usage does not just affect your local system. It can also impact how websites perform for you. Pages may load slowly or respond sluggishly. If you have ever experienced a slow website, high browser CPU usage could be a contributing factor.

For website owners, slow performance is a serious issue. If your site loads slowly because of browser issues, visitors will leave. To learn more about website speed and performance, read about Why Is My Website So Slow WordPress and how to fix it.

Preventing Future CPU Issues with Opera GX

Fixing the problem is only half the battle. Preventing it from happening again is just as important. A few simple habits can keep your browser running smoothly for the long term.

Limit the Number of Open Tabs

Try to keep your open tabs under 15 at any given time. Use bookmarks to save pages you want to revisit later. Opera GX has a built-in tab hibernation feature that puts inactive tabs to sleep. This frees up CPU and RAM without closing the tabs.

To enable tab hibernation, go to Settings and find the Performance section. Turn on “Tab hibernation” and set the time limit. Tabs that are not used for a set period will automatically go to sleep, freeing up resources.

Audit Your Extensions Regularly

Once a month, review your installed extensions. Remove any you no longer use or need. Disable extensions that you only use occasionally and enable them when needed. This keeps your browser lean and efficient.

Every extension you keep adds to the overall load on your system. Even extensions you rarely use still run background processes. Being ruthless about which extensions you keep makes a real difference.

Monitor Your System Resources

Make it a habit to check Task Manager or Activity Monitor regularly. If you notice Opera GX using high CPU again, you can catch the problem early. Early detection makes it easier to fix before it becomes a major issue.

You can also use Opera GX’s built-in GX Control dashboard to monitor resource usage in real time. This gives you a quick view of how much CPU and RAM your browser is consuming at any moment.

When to Consider Alternatives to Opera GX

Sometimes, despite your best efforts, Opera GX may not be the right browser for your system. If your PC is older or has limited resources, a lighter browser might be a better choice. Let us look at when switching makes sense.

If you have less than 8GB of RAM, a heavy browser like Opera GX might be too much. In that case, you might want to consider a lighter option. For tips on how much RAM your laptop needs, check out How Much Ram Is Good For A Laptop.
