How to Fix Roblox Lagging on PC

Is Roblox lagging on your PC?

Roblox is one of the best free-to-play gaming platforms out there. It allows you to play games and custom maps created by users or make your own world and invite your friends over. What’s even great about Roblox is that it doesn’t require much to run. 

This means that even entry-level or older systems should be able to handle the game. 

However, if you are reading this, you might be wondering why Roblox is so laggy on your PC, even if you have a decent gaming rig. 

This is one of the weirdest issues you may encounter on Roblox, mainly if your system handles the latest triple-A titles without breaking a sweat. Imagine having an RTX series card, and it can’t even play Roblox. 😀

While there are no specific reasons why this problem occurs, a few known workarounds might be able to help you out. 

Today, we will show you how to fix Roblox if it’s lagging on your PC. 

Let’s get started!

1. Restart Your Computer. 

If Roblox is lagging on your gaming PC, the first thing you should do is restart your system. Your graphics drivers or other system resources may have run into errors during runtime, which causes your GPU not to perform correctly. 

See the steps below to restart your computer: 

  1. First, open the Start Menu by clicking the Windows icon on the Taskbar
  2. After that, go to the Power Options tab. 
  3. Lastly, click the Restart button.

After restarting your system, go back to Roblox and see if the game is now running properly. 

2. Check Your Graphics Settings. 

Although Roblox is a reasonably light game to run, it can still put some load on your system if you crank the settings. For users with older or entry-level hardware, we suggest lowering your graphics settings if Roblox is lagging on your PC. 

To do this, follow the steps below: 

  1. While on the game, press the ESC key on your keyboard to access the options screen. 
  2. Next, click on Settings and scroll down until you see the Graphics Mode tab. 
  3. After that, change it to Manual
  4. Finally, lower the Graphics Quality.

Once done, close the settings and observe if you would still experience lags while playing. 

3. Close Unnecessary Applications. 

Another reason why Roblox is lagging on your PC is if you’ve run out of system resources. You can fix this by closing down unwanted applications on your computer to free up memory and reduce CPU and GPU load. 

Here’s how you can close unwanted programs on your system: 

  1. First, press the Windows + X keys on your keyboard to open the Quick Menu
  2. After that, click on Task Manager and go to the Processes tab. 
  3. Lastly, identify the applications you’re not using and close them.

Go back to Roblox afterward and see if the lag is reduced. 

4. Delete Your Temp Files. 

Temporary files on Windows work similarly to app caches on mobile devices. They enhance the performance of programs for a smoother interface, better FPS, and faster loading times. 

However, they can also get corrupted or accumulate over time and slow down your system. 

If Roblox is lagging on your PC, try clearing your temp files: 

  1. On your keyboard, press the Windows + R keys to launch Run Command
  2. Next, type ‘%temp%’ and click OK to open the folder. 
  3. Finally, select all the files in the folder and delete them.

Once done, restart Roblox and see if you would still experience lags.

5. Check Your Network Connection. 

The lag you’re experiencing from Roblox could be network-related and not an FPS issue. To confirm this, run a test on your network using Fast.com to measure its current upload and download speed. 

Speed Test

If the result suggests that your network is the problem, unplug your router from the wall outlet and let it rest for 5  to 10 seconds. After that, plug back in your router to the power source to restart it. This will refresh the link between your service provider and your modem. 

Restart Router

Once done, rerun the test on your network to check if you’re now getting the correct speeds based on your monthly plan. If you continue to experience issues with your connection, contact your ISP and ask them to fix the problem. 

6. Use a Wired Connection. 

When playing online games, it’s best that you use a wired ethernet connection to avoid lags and delays. Compared to wireless signals, a good old LAN cable will provide a much more stable connection to the internet. 

If using a LAN cable is not possible, we recommend moving your router near to your gaming PC or use a signal booster or repeater to improve your network’s quality. 

7. Change Your DNS. 

Another reason why Roblox is lagging is if your ISP’s default DNS server is experiencing technical issues at the moment. You can fix this by simply switching to other domain name servers such as Google’s DNS.

See the guide below on how you can change your DNS on Windows: 

  1. First, go to the Start Menu and look for ‘View Network Connections’. 
  2. Click Open afterward and right-click on your current network. 
  3. Now, choose Properties and double-click on Internet Protocol Version 4 (TCP/IPv4)
  4. After that, enable the ‘Use the Following DNS’ option and enter the following:
  • Preferred DNS Server: 8.8.8.8
  • Alternate DNS Server: 8.8.4.4

Go back to Roblox afterward and see if you would still experience lags. 

8. Reinstall Roblox. 

If none of the steps above worked out for you, the only option left is to reinstall the Roblox Player on your computer. This will ensure that you have the latest working version of Roblox installed on your system. 

Follow the guide below to remove Roblox on Windows: 

  1. On your computer, open the Control Panel and click on Uninstall a Program
  2. After that, locate the Roblox app from the list of programs installed on your computer. 
  3. Finally, right-click on Roblox and choose Uninstall
