This article will take you through some of the most common causes of high CPU usage in Roblox and how to fix them.

Why is the game using 100% of my CPU?

If you’ve ever run a game and seen the CPU usage shoot up to 100%, you might have wondered how this is possible. It’s not that the CPU is being used so hard by the game that it can’t handle any other tasks, but rather that it uses all available cores to run itself. This can happen for a variety of reasons:

Old game – You’re probably playing an older game that hasn’t been optimized for modern hardware. You can upgrade your CPU or play games optimized for old processors. Outdated OS – Older OSes don’t include support for multi-core processors. This will help reduce CPU usage when running these old games so the best option is to upgrade your OS. Resource-hungry game – Some games just require more processing power than others and will demand more resources than your computer can provide.

That being said, games that use 100% of your CPU are not necessarily bad. The reason they’re using so much CPU is to achieve the highest possible frame rate.  So just how much CPU should Roblox use? If you have a high-end gaming PC or laptop, then there’s nothing to worry about when running Roblox.  However, if your PC or laptop is below average and you want to play the game without issues, then it’s better that you know what kind of hardware and system requirements Roblox requires before playing it for the first time.

How do I limit Roblox’s high CPU usage?

Some basic things you can do to reduce CPU usage in Roblox include:

Ensure your PC meets the minimum system requirements to run Roblox. Close all other programs running on your computer while playing Roblox as they might be using up some of your computer’s resources. Uninstall any unnecessary programs.

1. Adjust your graphic settings 

If you have an old PC or laptop, then it’s possible that your computer may not be able to handle high graphic settings in Roblox. This will make your programs compete for the available CPU. In such cases, lowering the graphic settings will help you get rid of this problem as well as increase your frame rate and improve overall performance. SPONSORED

2. Disable Hardware Acceleration 

Hardware acceleration basically improves the performance of graphics and sound but takes up more resources at the same time causing high CPU usage in Roblox. The steps to disable it will be different for each browser, but with this example, you get the main idea.

3. Update your drivers

If you don’t know which drivers are causing problems on your PC because they’re not working properly anymore, manual updates can be time-consuming and still end up in a disaster. Luckily, there are other ways to approach this issue – a third-party tool. DriverFix is a powerful yet simple Windows driver updater tool. It can help you easily update your outdated display card drivers, network card drivers, and other hardware drivers to their latest versions.

4. Check for malware

5. Update your PC’s software

Is Roblox using CPU or GPU?

Roblox is not a game that uses graphics cards to render graphics although, in some instances, you may experience Roblox with high GPU usage. Normally, it uses your computer’s CPU to process the graphics, which means it’s less dependent on your graphics card. That being said, if your computer doesn’t have a good processor, you’ll notice lower framerates in Roblox games. If you want to improve your framerate in Roblox, one option is upgrading your CPU.  Another option would be to make Roblox use GPU instead of your CPU especially if you have a multi-core processor. You can turn on hardware-accelerated GPU scheduling to take off the load on your CPU if Roblox CPU usage is high. And as we wind up, you can also reset your browser or switch to gaming browsers if you’re still facing high CPU usage issues with Roblox.
