5 Chrome Flags to Disable for Improved Performance

Chrome is a great browser, but it can be a bit of a resource hog. If you’re looking for ways to improve performance, one of the best things you can do is use Chrome Flags.

Chrome flags are an excellent way to fully utilize the Chrome browser’s capability. However, enabling the flags is risky. Since they are experimental, they can create chaos in your system.

Instead of improving the performance, some flags can do the opposite and create problems. In this blog post, we’ll discuss such 5 Chrome Flags that are dangerous and should be disabled to improve performance on your computer.

What is a Chrome Flag?

Chrome Flags are a hidden feature in the Google Chrome browser. They are essentially settings that can be turned on or off to improve your browsing experience. Many of these settings are experimental, which means that they may change or break at any time.

The experimental settings also included the new feature that Google is currently testing and might release in the future updates if the testing goes right. So basically, if you enable and use any flag on your Google Chrome browser, you actually become a beta tester.

Apart from that, Chrome Flags also include a few advanced features for developers such as Javascript Debugging, GPU Accelerated Compositing, Experimental QUIC Protocol, and more. So, If you’re a developer or someone who simply enjoys experimenting with new under-cooked features, there are many amazing Chrome Flags available for you.

Enabling Chrome Flags is easy and only takes a few seconds. In the next section, we will show you how to enable them.

What are the problems with Chrome Flags?

While Chrome Flags can be really useful, there are also some potential problems that you should be aware of.

  • One problem with Chrome Flags is that they can be unstable. Since they are experimental features, they may change or break at any time. This means that you could enable a flag and then find out that it doesn’t work the way you wanted it to or that it causes problems with your browser.
  • Another problem with Chrome Flags is that they can be hard to find. Since they are hidden away in the settings, you might not even know that they exist unless you go looking for them. This can make it difficult to find the flags that you want to use or to figure out which flags are available.
  • Other than that, Chrome Flags can be confusing to use. Since they are designed for developers and power users, they might not be very intuitive for regular users. This can make it difficult to figure out how to enable or disable flags or how to use the features that they provide.
  • Moreover, some Chrome Flags can be considered privacy-invasive. For example, there is a flag that allows you to send Google your usage statistics and crash reports. This information can be used to target ads at you or to sell to third parties.
  • Finally, Chrome Flags can be dangerous. Since they can change the way your browser works, they could potentially cause problems with your computer if used incorrectly. This is why it’s important to be careful when using Chrome Flags and to only enable flags that you trust.

How to disable Chrome Flags?

If after enabling a flag the browser starts misbehaving, you can disable it in the same way you enabled it. Just navigate to the chrome://flags, search for the flag that is causing the issue, expand the drop-down menu next to its name and select Disabled.

If multiple flags are causing the problem and you don’t know which one is the culprit then reset all the flags by navigating to the chrome://flags and clicking on the Reset all button next to the search box.

5 Chrome Flags you should Disable

If you want your Chrome browser to remain stable and not affect your system performance, here are the 5 flags you must immediately disable if you have enabled them already.

Disable System Notifications Flag

This flag allows Chrome to display notifications on your system outside the browser. While that might not sound so bad, the problem is that these notifications can be very intrusive and annoying. They can also pop up at inopportune times, like when you’re in the middle of a presentation or working on something important.

So, if you want to get rid of these notifications, simply disable this flag. Your browser will still be able to show notifications, but they’ll only appear inside the Chrome window.

Disable Zero-Copy Rasterizer Flag

The Zero-Copy Rasterizer is a Chrome Flag that’s designed to improve graphics performance. However, in reality, it can actually slow down your browser and cause stability issues. In theory, enabling this flag might give you a slight performance boost when gaming or watching videos. However, it’s not worth the risk of stability issues.

So, if you want to avoid these problems, it’s best to disable this flag.

Disable GPU Rasterization Flag

The GPU Rasterization Flag is another one that’s designed to improve graphics performance. This flag uses your computer’s GPU to speed up drawing and rasterizing web pages. It also uses the system GPU to provide maximum performance on Chrome, especially while playing video. However, this flag can cause more harm than good. It can lead to crashes, freezes, and other stability issues.

Disable Threaded Scheduler Flag

The Threaded Scheduler Flag is a Chrome Flag that’s designed to improve performance by using multiple threads to schedule tasks.  However, in practice, this Flag can actually cause Chrome to slow down. If you want to improve your Chrome performance, you should disable the Threaded Scheduler Flag.

Site Isolation Opt-Out

Site isolation is a security feature that’s designed to isolate each website you visit from the other. This prevents websites from being able to access data or resources from other sites. While this is a great security feature, it can also cause performance issues. This Flag comes with the danger of exposing users to the Spectre CPU flaw, which hackers can take advantage of.


These are the five Chrome Flags that you should disable for improved performance. By disabling these flags, you can improve your Chrome browser’s stability and avoid any potential security risks. Do you have any other Chrome flags that you recommend disabling? Let us know in the comments below!
