Why is my Roblox so laggy, even on good PC in 2021?! You may wonder. Actually, you’re not alone. A number of players have reported that they experience inconsistent frames and lag while playing Roblox. Then how to fix Roblox lag? Don’t worry, we’ve gathered some fixes for you.

Try these fixes:

You might not have to try them all; simply work your way down the list until you find the one that works.

  1. Close unnecessary programs
  2. Delete temporary files
  3. Update your network adapter driver
  4. Use a wired connection
  5. Change your DNS settings
  6. Reduce your graphics quality on Roblox
  7. Delete textures

But before diving into troubleshooting, it’s recommended that you restart your PC and access the game again. Some lags on Roblox are easily resolved by simply restarting the game.


Fix 1: Close unnecessary programs

The game lagging is generally a sign of a slow game. This can be caused by having too many high-power programs using your system resources. For the most optimal experience, it is recommended that when you run Roblox, you close those other programs. To do this, take these steps:

1) Press Ctrl + Shift + Esc together on your keyboard to trigger Task Manager.

2) From the Processes tab, click the programs that you want to stop from running one by one and click End task.

Fix 2: Delete temporary files

As the name suggests, temporary files are the kind of files that store temporary data that is created by Windows itself or the programs that users use. But they take up some hard drive space which makes your computer slow, which can also impact the responsiveness to the connection. So to make your computer run smoother, you’re supposed to delete those files and it won’t cause any problems. Here’s how you can do this:

1) On your keyboard, press the Windows logo key and R at the same time to invoke the Run box.

2) Type %temp% and then press Enter on your keyboard.

3) Delete all the files in the temp folder. (Press Ctrl and A at the same time to select all the files. Then right-click and select Delete.)

5) Now go to your Recycling Bin from your desktop. Right-click on it and select Empty Recycle Bin.

After deleting the temp files, launch your game to check if the lag is reduced. If the problem persists, proceed to the next fix.


Fix 3: Update your network adpater driver

When your Roblox is lagging, it’s generally a sign of a slow connection. Your outdated network adapter driver can be the culprit and makes your game super laggy. To fix it, you need to update your network adapter driver, especially if you can’t remember when was the last time you updated it.

You can manually update your network adapter driver by going to the manufacturer’s official website to download and install the correct network driver for your system.

Fix 4: Use a wired connection

For gaming purposes, a wired connection is preferable over a wireless connection to the internet. Wireless connections are most susceptible to interference and aren’t as consistent as wired connections. More importantly, they increase latency. Therefore, if possible, use a wired connection when you play a game online.

However, if you don’t have an access to the wired connection, don’t worry, you can check out other fixes below.


Fix 5: Change your DNS settings

Sometimes your ISP-supplied DNS server might be slow or not properly configured for caching, which can slow your connection a little bit. And that might be the reason that your Roblox is so laggy. To save you time troubleshooting, you’re supposed to change your DNS settings.

Here we recommend using Google DNS:

1) On your keyboard, press the Windows logo key and R at the same time to open the Run dialog box.

2) Type control and then press Enter on your keyboard to open the Control Panel.

3) Click Network and Internet. (Note: make sure you view the Control Panel by Category.)

3) Click Network and Sharing Center.

4) Click on your Connections, whether it’s Ethernet, Wifi, or others.

5) Click Properties.

6) Click Internet Protocol Version 4 (TCP /IPv4) > Properties.

7) Click Use the following DNS server addresses:

For Preferred DNS server, type 8.8.8.8
For Alternate DNS server, type 8.8.4.4

Check the box next to Validate settings upon exit and then click OK.

After changing your DNS server, play your Roblox games and check if it’s less laggy. If this didn’t do the trick, proceed to the next fix below.
